For all the rambling, I'm happy to report that my SCHED_ULE + libthr
UP workstation feels noticibly more responsive when I have several
Mozilla tabs all loading pages simultaneously while I'm trying to make a
threaded Java IDE do something sensible.

It's possible that I'm actually seeing the impact of other changes that
have been committed in the last week, I suppose.

Ciao,
