Hi Fernando,

There is an explicit EmptyWorkingSet(), which probably just calls with MemSize -1.
In my example I set 128 MB, not the 64 MB you asked for...

On VirtualLock(): Haven't tried it yet, might be problematic with vfp.
Tell me, if you find something interesting.

Yup. Tell me more about your app / needs first...
