I know.  I didn't realize that the map was that large. It's for
Indexing memory objects to threads.  I did something similar under
Delphi but now recall limiting the size from [-1..99999] or something
like that.  But that's in a 32 bit OS.  Doing it that way isn't going
to work.

I've got another way already.  I just didn't relate the size of the
actual structure.
