The exit status may exceed 255 in some cases (return); even though it seems
unwise to rely on this, it is also unwise to assume that $? is always

This avoids using non-standard behaviour of the old (upto FreeBSD 7) TTY

implementation directly calls getrusage() to get the times because this is more
convenient.

not its argument (as is the case for the -c option). Also
