Modified files:
sys/kern kern_fork.c
Log:
Put on my asbestos underwear and commit the patch that I posted to -arch
some time ago that changes kern.randompid from a boolean to a randomness
range for the next pid assigment. Too high causes a lot of extra work
to scan for free pids, and too low merely wastes randomness entropy. It's
still possible to select a completely random range by using PID_MAX (100k)
or -1 as a shortcut to mean "the whole range".
Also, don't waste randomness when doing a wraparound.
