// Handling SIGTSTP keeps time-keeping for progress indicator correct
// if xz is stopped. It requires use of clock_gettime() as that is
// async-signal safe in POSIX. Require also SIGALRM support since
// on systems where SIGALRM isn't available, progress indicator code
// polls the time and the SIGTSTP handling adds slight overhead to
// that code. Most (all?) systems that have SIGTSTP also have SIGALRM
// so this requirement won't exclude many systems.
