> On Windows vm_unmap_mem() fails to release memory back to OS. STD_FREE uncommits the
relevant nos, mos etc. spaces, these heap regions are now unmapped and VirtualFree cannot
be called on these locations. Moreover, VirtualFree with MEM_RELEASE nees to be be called
from the exact allocation base, or the call will fail. Added an assert so that Memory tools
are not the only way to catch the error.
> Don't commit until gc people review.
