it seemed safer at first if I didn't have to worry about the procs
preempting each other (and appart from that dial() bottleneck, I don't
need them to), that's why I started with threads. I was thinking of
sticking to threads and not using procs until I really do need them. But
yeah, no real good reason not to switch to procs if that's the best way
to go in that case.
