72eda149c5 Use minor GC code to move GC coop result to heap 
This allows the code to move any object to the heap, instead of the previous hack. There may be more overhead calling the full minor GC code, however, most objects should already have been moved and by definition this would only happen after a function has blocked for a length of time. So, both should minimize the additional overhead.

be13df2abb Perform deferred free of thread data 
Mark a mutator's thread as old when a thread is terminated, and free it at a later time. This is done to prevent race conditions with the collector thread, which could be in the middle of working with a thread's data.

15ac239d2f Mark current continuation during GC coop 
Mark both current cont (gc_cont + args) as well as all moved objects during cooperation. Trying to prevent cases of valid objects being collected when they should have been part of the continuation chain (IE, parens in read:parse).

e994d4aa76 Do thread locking outside of gc_mark_gray 
Changed the locking to attempt to avoid race conditions where not all of the heap objects have been moved prior to the collector staring to process them.
