One way to hack this functionality into NT is to use the SOON command.  It
basically says, "Run some command in X seconds".  It is essentially an
interface to AT.  

You can end your program with a SOON command to run it again in a little
while.  As long as the chain runs unbroken, you're in luck.  This of course
is a problem if your program doesn't complete or any number of other
issues.  I'm frankly not a fan of this approach.

Sleep is quite lean on the CPU.  If your program sits on a big pile of
memory, this could be an issue, even with paging.
