A test on my laptop whilst flying over I saw the same performance numbers
for single byte notifications for pseudo IPC on Windows and real IPC on
Linux:  ~6 million messages per second.  If that is true and performance
degrades significantly worse with larger messages on the pseudo IPC front
then the logically extension is to use shared memory for the payload but
keep the socketpair for the notification.
