[PATCH] pid-max-2.5.33-A0
This is the pid-max patch, the one i sent for 2.5.31 was botched. I
have removed the 'once' debugging stupidity - now PIDs start at 0 again.
Also, for an unknown reason the previous patch missed the hunk that had
the declaration of 'DEFAULT_PID_MAX' which made it not compile ...
