Michael Kerrisk 4f6d71a1fc signal.7: Timeouts make socket interfaces non-restartable 
If setsockopt() is used to set a timeout on a socket(),
then the various socket interfaces are not automatically
restarted, even if SA_RESTART is specified when
establishing the signal handler.  Analogous behavior occurs
for the "stop signals" case.
