Thanks.  I did apply your patch, and also Hans' patch for the extra
UNLOCK.  They didn't seem to help.

Incidentally, I tried swapping in a vanilla conservative boehm.cc that
simply calls GC_malloc and ignores the bitmap, just to rule out some
things.  It didn't change the behavior of gc in this regard.
