Seeing Jack's reply to this, and not having any BSD handy to look at
things on, I'll have to let you two argue on that subject. But
shouldn't a working pthreads be generally a prerequisite for the Linux
emulation layer that the BSDs tout?

I had heard of pthreads working on a lot of things, and was going to
go dig up your exact patch when I remembered pthreads. Doing the
writer as a thread instead of a child process would be much more clean
IMHO, but if there really are portability problems with doing it as a
thread, I won't (or maybe #ifdef or conditionally compile a threaded
implementation for those platforms that support pthreads, but that
gets messy quickly).
