Hi Folks,

I ignored my own good judgement completely earlier
today and wrote this:

This turns out to be completely boneheaded, as I've now
been informed by people who really know how this works.

Windows is no different from UNIX or Mac or any other
operating system. Dynamic memory allocation is pretty
much the same on all of them -- malloc. And there is
just no "general" was to do the memory allocation and
give unused memory back to the OS.

Sorry to have gotten your hopes up. The good news is that
you can sell all that Microsoft stock you just bought at
a nice premium, probably. :-)

Cheers,

David
