*** Notes ***

**** api2/configapi layer ****

    This is used by all the UNO wrappers, and features a much simpler
API, works on both NodeGroup & NodeSet node references
[NodeSetInfoAccess eg.]

	+ All operates on:
	    + configuration::Tree references

	+ apinodeaccess.cxx:
	    + makeElement
	    + makeUnoElement
	    + GuardedNodeAccess:
	+ accessimpl.cxx:
	    + implGetByName
		+ takes a GuardedNodeDataAccess lock.

	+ calls into 'configuration' API
	    ::configuration::getChildOrElement
	    ::configuration::validateAndReducePath
	    ::configuration::getDeepDescendant

	+ apifactory.cxx:
	    + configapi::Factory::
		+ makes UNO proxies for things

	+ apifactoryimpl.cxx:
	    + ReadOnlyObjectFactory::doCreateSetElement
		+ creates set elements.

	+ groupobjects.cxx:
	    + OSetElementGroupInfo

	+ apiaccessobj.hxx:
	    + OSetElement
		+ instantiates an ApiTreeImpl

	+ apitreeimplobj.cxx:
	    + ApiTreeImpl::ApiTreeImpl + ::init
	    + adds notifiers & all manner of gubbins

	+ notifierimpl.hxx
	    + 1 member: a SpecialListenerContainer

	+ listenercontainer.cxx
	    + manages XEventListener, XContainerListener,
	      XChangesListener, XPropertyChangeListener,
	      XVetoableChangeListener [etc.]
	      XPropertiesChangeListener
**	    + the vetoing - requires synchronous
	      listening (always?) ... 

	    typedef SpecialListenerContainer <SubNodeID,SubNodeHash,SubNodeEq,SubNodeToIndex> SpecialContainer;
	    ...
	    typedef cppu::OMultiTypeInterfaceContainerHelperVar< Key_,KeyHash_,KeyEq_ >	SpecialContainerHelper;
	    + Slowness via  OBroadcastHelperVar<> m_aSpecialHelper
	    	    + 100 elements ?
		    + default bucket count:
			+ we -usually- only use 1 element so ...

	+ cppuhelper/inc/cppuhelper/interfacecontainer.h
	    + OMultiTypeInterfaceContainerHelper
	    + interesting: can add / remove same thing
	      multiple times [ with a simple ref-count ? ]

	+ since each node has an (allocated) NotifierImpl anyway
	    + why not let the node track listeners itself ?
	    + far easier to find & manage surely ?

	+ what are in these buckets ?
	    + are there 100 buckets to clear (each?)
	    + 36million cycles

	+ NotifierImpl much loved by:
	    + broadcaster.cxx
	    + confignotifier.cxx
	    + apitreeimplobj.cxx

	+ void configmgr::configapi::NotifierImpl::add(const configmgr::configuration::NodeID&,
	       const com::sun::star::uno::Reference<com::sun::star::lang::XEventListener>&)
	    + called for every node [ for some reason ]

	+ propertiesfilterednotifier.cxx:

+ datalock.hxx: DataLock (typedef'd to Lock)

   
it *seems* that 'isValidAddress'
    + burns 25% of time with debug build - is this
      the use of all this book-keeping state ?

    + SimpleCheckingHeapManager:
	+ only 2 instances (static):
	    + cacheHeap()
	    + localHeap()

    + Question:
	+ is the batch freeing of a 'Heap' relied on ?

* Strategy:
    + rip out the custom allocator crud ...
    + [ totally unnecessary ]
	+ Address - hunt/destroy (?)
    + hoist any 'Heap' stuff up as a 'shared lock' class (?)
	+ if it's used ...
        + Heap used for batch freeing too (!?) [urgh]

    + write a test tool ? [ for performance ]
	+ [ automated regression tests ? ]

TODO:
    + remove 'realloc' - never called in anger ?
    + 'anydata' should be an UNO type [ surely ... ]

    + calls to 'allocate'

        I'm also looking at the Subtree set usage:

        http://go-oo.org/~michael/sortedsizes.ods

        My concern here is the 16bytes per RBTree node (used in the set), at
least allocation here shows up on the profile.

        It seems that 90% of these sorted sets are 8 items or less, and thus (I
suspect) rather fast to search, well, at least indistinguishable from
the order of the Set. The RBTree overhead for these <= 8 sets is ~250k
(malloc), overall 500k. I'm sure we can do better.

    + a sorted vector instead !?
