Mike Silbersack cc6712ea04 A few misc forkbomb defenses: 
- Leave 10 processes for root-only use, the previous
  value of 1 was insufficient to run ps ax | more.
- Remove the printing of "proc: table full".  When the table
  really is full, this would flood the screen/logs, making
  the problem tougher to deal with.
- Force any process trying to fork beyond its user's maximum
  number of processes to sleep for .5 seconds before returning
  failure.  This turns 2000 rampaging fork monsters into 2000
  harmlessly snoozing fork monsters.
