There was a recent copy of Java on Linux from the Java developers journal.
I only mention this because Ruby is developed on Linux and is not (yet??)
ported to Sun.  Linux threads are heavy weight to the extreme, they are just
disguised processes.  The Sun model is LWP internal to each process (of
course).  Solaris, btw, will be open sourced pretty soon (or already is)

Many dont like multithreading, and I have yet to write in it, but I would very
much like to.  The primary reason would be to share complex structures between
server connections w/o the bother of serializing and locking shared memory.

From the administrative point of view, multiprocessing is very controllable
whereas multithreading presents a black box.
