Unlikely, if it's taking *all* the CPU.

It sounds like a socket is in a wierd state where select() returns
immediately on it, but Squeak is keeping the socket open.  Thus the "go
to sleep" primitive never actually sleeps.  I haven't duplicated it, but
maybe it's because my Swiki image is pretty old and some image-level
issue is happening here.

Out of curiousity, do you see the same thing on a non-Swiki image?

Also, are you using the headless binary (compiled with -DHEADLESS), or
are you using "squeak -headless" ?

Oh, by the way, don't run it in a MVC project.  There's some bug
involving the virtual screen being too small ("headless" mode actually
pretends that there is a display, and just doesn't show it on the
physical monitor.)

Unlikely to help here, though it's a great way to learn a lot about
what's in your image!
