Oops.  Mental typo.  Yeah, but the machine I use most often doesn't have
Streams (we have the add-on package but have yet to install it because the
network board we want to use it with is so unreliable...).

Non-preemptive multithreading:  yesterday at work, I laid out a nonpreemptive
thread system of sorts.  It's not particularly easy to rewrite something big
like Perl to use the implementation I came up with, but it's there.  (I have
some fairly bizarre convolutions between a 4GL and a Prolog interpreter at
work to get a job done --- bizarre it may be, but it runs 20x faster than the
4GL-only version.  The threading is for the interface to the Prolog, so if
necessary I can have more than one running.)
