commit 6c6072ba8b079e6f5caa38b011a6f4570c14ed38
Author: Darren Tucker <dtucker at dtucker.net>

    See if SA_RESTART signals will interrupt select().
    
    On some platforms (at least older HP-UXes such as 11.11, possibly others)
    setting SA_RESTART on signal handers will cause it to not interrupt
    select(), at least for calls that do not specify a timeout.  Try to
    detect this and if found, don't use SA_RESTART.
    
    POSIX says "If SA_RESTART has been set for the interrupting signal, it
    is implementation-dependent whether select() restarts or returns with
    [EINTR]" so this behaviour is within spec.
