Hmm, deathly silence. Would anyone in the Condor core team care to take a
look at this, and/or explain the logic behind the sleeps in the algorithm for
assigning process ids?
It's amazing how much pain a 12-second delay can cause when it's repeated
over and over again :-(
Sorry for not replying to this earlier...
Anyhow, we're investigating whether we can reduce (or entirely remove) the
12-second sleep without running into problems. I think the conversions
between seconds and clock ticks *are* consistent between the various code
paths; but the real question is whether we need the 12-second sleep.
It's certainly a bug, though, that the value of DEFAULT_PRECISION_RANGE
will get changed if the code gets called twice. (That shouldn't actually
be causing a problem right now, because we only call the relevant code on
startup, but it still should be fixed.)
(This code was written by someone who's no longer with the CHTC Team, and
unfortunately it's not real well understood by any of the current team
