When profile_time (DOS only) is in effect,
I have to keep track of time myself.
By default, I expect the system to interrupt me 100 
times per second. On Windows ME/98/95 this seems to happen,
and the time is calculated correctly. On XP it looks like
the system may be neglecting to interrupt me as often as
it should. On a test I just tried, the elapsed time was off by 8%.
(on XP only). I guess XP's DOS emulation is a bit flaky around the
edges. I'll keep this in mind. Your profile results should still 
be valid.
