/* Make the process sleep for SECONDS seconds, or until a signal arrives
and is not ignored. The function returns the number of seconds less
than SECONDS which it actually slept (zero if it slept the full time).
If a signal handler does a `longjmp' or modifies the handling of the
SIGALRM signal while inside `sleep' call, the handling of the SIGALRM
signal afterwards is undefined. There is no return value to indicate
error, but if `sleep' returns SECONDS, it probably didn't work. */
