Yes. select will wake up on pipes. (select's emulation only works on socket in Windows, though.) I wouldn't use select directly, I'd use via IO::Select.

Pipes are usually used between processes, but they don't have to be. Just make sure you don't fill up the pipe, as that would block the only process that can empty it. I wouldn't bother with IO::Pipe. It doesn't add anything good over pipe.

If you're using threads, you should look at Thread::Queue.
