+/* Some system calls may be interrupted and fail with errno = EINTR in the
+ following situations:
+ - The process is stopped and restarted (signal SIGSTOP and SIGCONT, user
+ types Ctrl-Z) on some platforms: Mac OS X.
+ - The process receives a signal for which a signal handler was installed
+ with sigaction() with an sa_flags field that does not contain
+ SA_RESTART.
+ - The process receives a signal for which a signal handler was installed
+ with signal() and for which no call to siginterrupt(sig,0) was done,
+ on some platforms: AIX, HP-UX, IRIX, OSF/1, Solaris.

+ This module provides a wrapper around write() that handles EINTR. */
