102244be21 Issue #304 - gc_copy_obj must to populate bignums 
Even without bignums in the nursery we still need this code in place since gc_alloc calls it, and otherwise all of the callers would need to ensure bignums are properly initialized. There may be an opportunity here for optimization, but let's make sure everything works first!

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!
