* the periodic SIGALRM clocks. On some platforms (such as
* HP-UX and SINIX) an interrupted select() system call is
* restarted with the originally specified timeout, ignoring
* the time that has elapsed. If a select() call is interrupted
* repeatedly, it will never time out. (See Bugzilla bug #39674.)
