Maybe this has been answered already since I haven't been following
this newsgroup for a few days.

The way I solve this is to include a common unique to the routine
needing random numbers and store the random number seed in that
common. This is only needed if the routine is called multiple
times with more than one call per second. If you generate all the
needed random numbers in the same call this problem does not occur
(as you stated above).
