I'm not sure what's happening on your systems.  It is possible your heap
is filled with pagelocked objects, but real unlikely.  Are you calling
GlobalAlloc(), or are you calling GlobalCompact(0)?  Note that under
Enchanted mode, GlobalCompact() doesn't really compact the heap, it just
tells you the largest block you can get _without_ compacting.  This is
on purpose, since compacting the heap on a page-swapping system takes a
lot of time and disk access.  If you really want a lot of memory, just
allocate it.  This will convince Windows that you are serious, and force
heap compaction.

I'm able to routinely allocate 4 MB (and sometimes 8MB) on my system with
8MB ram, (6MB available to Windows).  You should be able to, also.
