Signals and context switches

[Eliot Moss]

Why not uses pipes? Sending one character down a pipe (or pty or whatever) can
be the signal; the receiver can read and toss the character. You can use
select to detect the arrivial, and also arrange for SIGIO to be delivered if
you need rapid asynchronous handling of the notification.
