Thanks Fergus for pointing this out. I was playing
by ear: "Does it work in Hugs?"
I rarely use (if ever) "unsafePerformIO" in any of my code,
but this time the application demanded such a heavy usage
of time stamps that a "lightweight" method of IO unwrapping
seemed to be quite handy. It turned out not to be :-)
