Sorry, but this is probably not the best thing to look at. First of all,
it's not portable (it uses the system time under DJGPP, the process ID on
other systems where available, and doesn't appear to work under EMX).

Then, the unit (and especially the random algorithms and data sizes) are
particularly for compatibility with BP's random generator, nothing else.

So, a portable way to get fractions of a second would be a fine thing
(micro seconds will not always be possible; under Dos, e.g., the
resolution is 1/18.2 seconds, unless you do direct hardware manipulation)...
