that is quite odd. The entries are recycled, but when _pContainerChanges
is set to point to one (in FC::registerChangedContainer()) it also sets
the uiEntryDesc.

ReflexiveContainer::clearChangeEntry(), called from:
- ChangeList::doClear()
- ChangeList::doApply(true)

Ok. If you put a ChangeList::dumpListSizes() right before that, what
numbers do you get? In particular IIRC if 'UC_S' > 0 (i.e. there are
uncommitted changes) calls to the containers ::changed() function may be
lost.

Hmm, that is sort of consistent with _pContainerChanges not being reset.
The next change after the reset should cause the it to be put back on
the CL changed dump.
I think it would be quite interesting to find out why
ReflexiveContainer::clearChangeEntry() is not called (or why it doesn't
do anything), to me that currently seems like the root of the problem.
