Good suggestion, and that actually what happens right now :-)

But I also want something a little more formal. I still feel a little
attached to the common block implementation. Still purely optional on
the part of the user. We'll see multi-threaded IDL coming from a mile
away, if it ever comes. I'll deal with it then.

Right now I multiprocess MPFIT on my dual-CPU machine by running two
IDL sessions. Works great!
