Re: Signal on process end

How best do I see when the process has finished?

You try to read from it and get undef.

Yes, well that implies that I have to find a way of polling it
without blocking.

I was hoping that there was a watch or event I could use.

See `perldoc -f select`.

I was also wondering about a thread to do

waitpid($pid, 0);

and then destroy the dialog.

But I was hoping I could avoid using threads.
