So far this seems very plausible.  Most of these failures, on days when they
did happen, were pretty reproducible.  I just tried it and it segfaulted.
Then I recompiled with the fix and it didn't.

Of course this isn't definitive proof, but it's a good clue that possibly
this does indeed fix the weak GC stuff.

Cheers,
