Async::Interrupt is a Perl module that implements asynchronous interruptions,
similar in nature to UNIX signals, in a cross-platform manner. Modules might
want to run code asynchronously (in another thread or from a signal handler)
and then signal the interpreter on certain events. One common way is to write
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.
