+     "@code{Async::Interrupt} implements a single feature only of interest
+to advanced perl modules, namely asynchronous interruptions (think \"UNIX
+signals\", which are very similar).
+
+Sometimes, modules wish to run code asynchronously (in another thread,
+or from a signal handler), and then signal the perl interpreter on
+certain events.  One common way is to write some data to a pipe and use
+an event handling toolkit to watch for I/O events.  Another way is to
+send a signal.  Those methods are slow, and in the case of a pipe, also
+not asynchronous - it won't interrupt a running perl interpreter.
+
+This module implements asynchronous notifications that enable you to
+signal running perl code from another thread, asynchronously, and
+sometimes even without using a single syscall.")
