  Log Message:
  -----------
  Further improve kdc child process management

- Simplify child process creation rate limit by moving
  select_sleep() to happen right after the parent fork().

- Consider child pid table slots to be empty if the pid is
  non-positive, rather than just -1 or just 0.

- Log warnings should we ever spawn a child with no free
  slot to track it, or reap a child that does not match
  a tracked slot.
