Since process filters are currently processed "asynchronously", it would
seem like a natural idea would be to create a thread for each process,
and let that thread run all the process's filters and sentinels.

While I'm here, there's of course another relevant test case: open Emacs
on several ttys, and run some long-running commands like indent-region
in each (in different buffers at first, and then in the same one, but
on different parts of the text, ...).
