WriterThreadPool, WriterThreadSpawn, Base, and potentially
other rarely-used concurrency options experienced slow shutdowns
due to the destruction of a listener socket failing to wake up
a thread in IO.select.
Send ourselves a signal to interrupt the IO.select call in
the main thread to force the wakeup.
