I'm open to ideas. :) The "classic" non-Perl way would obvioysly be
just providing a popen() that returns an instance of type file.

No. My hope is that current OSs can deal well with *many* threads, in
particular if they are all of low load. What we'll eventually need
though is a way to cleanup threads no longer used. That's not done

That said, adding one thread per IOSource doesn't make much of a
difference, it's the logging that creates potentially many threads.

If things really don't work out, we'll need to swtich to
one-thread-per-stream mode, but that gets more tricky on the backend
side. I would prefer to avoid that.

I'm not surprised. :)
