Mike,
I found this weird as well. (although we should be talking about this on
comp.os.unix.*, but who cares...) I believe the system goes through a
fork/thread manager. When that happens it takes the 501 slot. After all the
kids have been spawned, then it says, " all is well " , and then croaks.
Therefore, an empty spot in between will occur.
If this is wrong, let me know.
Thanks
Jeff

Thinks't thou existence doth depend on time?
It doth; but actions are our epochs; mine
Have made my days and nights imperishable,
Endless, and all alike, as sands on the shore,
Innumerable atoms; and one desert,
Barren and cold, on which the wild waves break,
But nothing rests, save carcasses and wrecks,
Rocks, and the salt-surf weeds of bitterness.
