Don't forget that patches which aim to reduce overhead are best when
accompanied with benchmarks which show the effect of the reduction.

-       pacl = (PACL) LocalAlloc(LPTR, dwNewAclSize);
+       pacl = (PACL) HeapAlloc(hDefaultProcessHeap, 0, dwNewAclSize);

These calls are not equal, the LocalAlloc calls zeroes out the allocated memory
but the HeapAlloc does not unless the HEAP_ZERO_MEMORY flag is passed.  I
haven't read the code enough to know if that matters, but it seems relevant to
at least discuss.
