DURATION is a floating point number with an optional suffix: 's' for
seconds (the default), 'm' for minutes, 'h' for hours or 'd' for days.
If the command times out, and --preserve-status is not set, then exit
with status 124. Otherwise, exit with the status of COMMAND. If no
signal is specified, send the TERM signal upon timeout. The TERM sig-
nal kills any process that does not block or catch that signal. It may
be necessary to use the KILL (9) signal, since this signal cannot be
caught, in which case the exit status is 128+9 rather than 124.
Some platforms don't curently support timeouts beyond 2038
