+<p>This function furnishes a workalike for signal(2) but
+which internally invokes sigaction(2) after certain
+sa_flags are set; these primarily to ensure restarting
+of interrupted system calls. See sigaction(2)  It is a
+aid to transition and not new development: that effort
+should employ sigaction directly. [gosgood 18.04.2000]</p>
+<p>Cause <em class="parameter"><code>handler</code></em>
+ to be run when <em class="parameter"><code>signum</code></em>
+ is delivered.  We
+use sigaction(2) rather than signal(2) so that we can control the
+signal handler's environment completely via <em class="parameter"><code>flags</code></em>
+: some signal(2)
+implementations differ in their semantics, so we need to nail down
+exactly what we want. [austin 06.04.2000]</p>
