Description (last modified by fdupont)

in signal_set.{h,cc}:

    /// Prior to invoking the handler, it sets signal action for the
    /// given signal to SIG_IGN which prevents any repeat signal
    /// occurrences from queuing while the handler is executing.  Upon
    /// completion of the handler, the signal action is restored which
    /// re-enables receipt and handling of the signal.

This should not be applied to SIGCHLD as ignoring it has a special meaning we don't want.
