hmm, then I tend to make it an error: prlimit acts too similar to
ulimit, but the *big* difference - and therefore the *big* trap for
the user - is that ulimit is a shell builtin which affects the current
shell process whereas prlimit runs in it's own process and, as a result,
will just do not have an effect without a PID.

Have a nice day,
Berny
