Can't we find some solution for this, ie. patch boehm a little bit.

I think all we need to do is replacing GC_stop_world() and GC_start_world() with our own
functions.  This could be done with a function vtable, so we'd get something which we
could submit to the boehm people for inclusion in their next release.
