Log message:
grdc(6): implement timeout with alarm(3)
grdc(6) has an optional argument indicating a timeout in seconds.
For example, one could do:
$ grdc 60
to to tell grdc(6) to run for sixty seconds and then exit gracefully.
As implemented, however, the timeout may occur too early or too late
if the system clock is reset with settimeofday(2).
To avoid this problem we can instead use alarm(3) and a signal handler
to implement the timeout. alarm(3) is unaffected by settimeofday(2).
