Limit CPU usage for an application/process
Authored by: CoolerQ on Feb 02, '11 10:29:34PM

You're not quite right there... first off, it's SIGSTOP and SIGCONT, not SIGSTART, but I'll assume that's a typo. SIGSTOP isn't what is sent by the terminal when you press control-Z; that's SIGTSTP, which stands for "Tty SToP"; the signals are different because SIGSTOP cannot be trapped by the program you are controlling.

Your point about this interfering with the operation of some programs is, however, quite valid.

(Amusingly, Wikipedia has an article for each POSIX signal, including http://en.wikipedia.org/wiki/SIGTSTP )
