Unfortunately adding unused helper functions isn't the right way to
split up the patches.  You'll need to find a way to break up the
functionality while incrementally adding these things.

GetProcessHeap() is cheap, you don't need to bother caching it.  You
may want to consider using the standardized heap_alloc() / heap_free()
helpers.
