I hadn't seen that your original bug report was for preemption.  This 
makes it easier to "debug" it just by postponing it after 2.2.

Preemption (more appropriately named automatic time-sharing preemption, 
because I/O multitasking *is* preemptive) support is still not ready for 
prime time.

Browser requires Blox which requires BloxGTK, so you get a whole mess of 
half-Tk, half-GTK blox...

Anyway 2.2 will still use BloxTk by default, because BloxGTK does not 
support much more than the browser.  GTK will be enabled by default, but 
not for the browser.

I will put out a final tarball this week.
