Yes, yes it is.  I have a branch that has changes to interrupt threads where 
you can have an interrupt handler reschedule itself.  That prevents this class 
of problems as the handler always runs in the interrupt thread.

I really should get that patch into HEAD someday.  I've posted it to arch@ 
twice now I think. :(  It also fixes interrupt filters to really work properly 
and be on by default.
