HeapWalk generated FIXME

[Lanny DeVaney]

Excuse the newby question, but it appears HeapWalk in memory/heap.c 
calls RtlWalkHeap in dlls/ntdll/heap.c and this in turn is generating 
fixme messages (lots of them since it appears this is called in a loop.)  

Can someone enlighten me as to what the problem is, and why one would 
see the "not fully compatible" fixme messages from RtlWalkHeap.

Thanks,
