+/* Some system calls may be interrupted and fail with errno = EINTR in the

+     - The process is stopped and restarted (signal SIGSTOP and SIGCONT, user

+     - The process receives a signal for which a signal handler was installed

+       SA_RESTART.
+     - The process receives a signal for which a signal handler was installed

+       on some platforms: AIX, HP-UX, IRIX, OSF/1, Solaris.
