* This function sends the signal specified by signo with the signal

* Only one pending signal (per signo) is retained. This
* is consistent with POSIX which states, "If a subsequent
* occurrence of a pending signal is generated, it is
* implementation defined as to whether the signal is
* delivered more than once."
