Interesting - I was quoting MS's doc on the virtual memory management:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnanchor/ht
ml/memoryank.asp

When I asked the question on a number of fora, no-one could give me a
guaranteed mechanism that would work under Windows. 
In addition, there's a block diagram in the article I reference that clearly
shows the memory manager beneath all memory
management APIs - which also implies a programmer cannot get full access to
the memory management functions.

Of course, the documentation may not be correct ...
