The code crashes even with these changes reverted, so something else is clearly wrong.

1343490c9b Experimental change to fix GC crashes 
I think the real problem may be that we mark globals before waiting for the mutators to transition to the new Mark color. If we wait until after a minor gc to update the mark color, there is a window where the mutator may sweep, and this is after globals have been marked. So the newly marked objects may be accidentally freed by sweep!

5216131309 Temporary (?) failsafe in gc_sweep 
Also account for collector's mark color when sweeping old objects. Sucks to have to make 3 comparisons but its better than risking accidentally freeing a traced object!
