pid_max madness

[Grzegorz Piotr Jaskiewicz]

Let's do:
#echo "-1" >/proc/sys/kernel/pid_max
#cat /proc/sys/kernel/pid_max
-1
#

Madness, isn't ?

I guess that isn't what author ment it to behave like.
Anyway, does it mean that after max unsigned value is reached pids are 
going to be negative in value ??
