  Branch:      sys/kern  RELENG_2_1_0
  Modified:    sys/kern  kern_proc.c kern_sysctl.c
  Log:
  Implemented zpfind() which returns the struct proc * of a zombie PID.
  Used the above as part of a fix for an architectural flaw in the way that
  sysctl_doproc works. sysctl_doproc can block while traversing the proc
  lists and the state of the list may have changed during this time. The
  fix is to check that the process still exists, and if not, restart the
  loop from the beginning.
  
  Note that I don't understand how to unwind SYSCTL_OUT things in -current,
  SO SOMEBODY ELSE WILL HAVE TO IMPLEMENT THIS FIX THERE!!! (Poul?)
