98a18a225a Handle old stack objects on write barrier 
The gc_mut_update write barrier should not assume that the old object is on the heap, lets also gray the old object if it happens to be on the stack. Worst case, we mark an extra object here or there. Best case, may prevent gc_allocated_bytes receiving forward pointers.

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.
