True, but Python seems to be the *best* place to tackle this problem,
at least to me. It has a large pool of developers, a large standard
library, it's evolving, and it's a language I like :). Languages that
seamlessly support multi-threaded programming are coming, as are
extensions that make it easier on every existent platform. Python has
the opportunity to lead that change.

I knew somebody was going to say that! I'm pretty busy, but I'll see
if I can find some time to look into it.

I was hoping to get a constructive conversation on what the structure
of a multi-threaded python would look like. It would appear that this
was not the place for that.

No, it's not, and even fewer allow the scheduler to change the
priority dynamically. Linux, however, is one that does.
