The process limit is the maximum number of processes allowed to run
simultanious ! This won't affect your execution speed and should not be set
to "unlimited" because simple fork bombs could bring your system down to a
halt (like this one: ":() { :|:& };:", try setting "ulimit -u 200" and run
this script as a user and then do "ulimit -u unlimited" and run it again...
but save your work first ;-)
