Yeah, something funky is going on here, but I'm not sure what either. For
example, with VC's debug heap turned on, I got the following warning when
opening a second document from a fresh CVS build:
HEAP[AbiWord.exe]: HEAP: Free Heap block e10b10 modified at e15110 after it
was freed
Ick! When I ignored the assert, things continued to work, which is even
spookier. :-(

Again, I'm not sure what's going on here -- anybody running Purify or
BoundsChecker might get some better information -- but here's one place to
look:

Any caching logic which doesn't know how to clean up after itself may also
have problems with reuse. Just a wild-eyed guess, though.
