4e5266a78d Do not gc_heap_align result of gc_allocated_bytes 
This function already heap aligns it's return value so there is no need to use the alignment macro again.

ea2550a882 Issue #199 - More efficient memory usage 
Only use a single int on the heap to store the number of huge heap allocations. There is no need to track allocations on the other heaps, at least at this time.

95e15dd3c2 Issue #199 - Initiate GC using huge GC alloc count 
Free space does not work for huge heaps since often they are allocated on demand as a full page at a time. But if more than X huge pages have been allocated, it is probably a good time to initiate a major GC.

3f75e8d231 Mark objects when collector cooperates 
When the collector cooperates for a mutator it needs to mark any heap-collected objects that are stored within the mutator's data object. This prevents problems where these objects (which are essentially per-thread global roots) are incorrectly collected.

2b04c3b253 Set gc_cont and num args prior to blocking 
This change shouldn't hurt anything and guarantees the collector thread is not trying to use gc_cont before it is set properly.

33e55c3cce GC tweaks to avoid free/grow thrashing 
Attempt to prevent thrashing the GC during earley benchmark by:

- Allowing a larger max page size
- Only freeing huge pages. This prevents thrashing where pages are freed only to be immediately reallocated when the heap is grown after sweep.

Longer term it may be necessary to allow freeing of pages by being more intelligent about things.
