It is tricky.  For example, a dialog box might have a memory leak when
you click "cancel" but not when you click "OK" to exit it.  The leak
can depend on the exact steps taken by the user and the exact path
through the code.  We can never test all paths.

Maybe one of the long-time OpenOffice developers know an answer to
this:  Have we ever considered having a custom memory allocator with a
separate pool of memory for each loaded document?  That way, when we
close a document we can just free the entire block and avoid any
memory leaks?  We did this with SmartSuite years ago, and it was a big
help.
