Do those "permathreads" spend a lot of time in an inconsistent state when it 
would be dangerous to stop them? I'm still wondering about the latch 
solution, you could possibly sprinkle those long running threads with waits 
on the DRb latch to emulate stopping the threadgroup. Of course, that might 
end up looking really, really ugly with remote debugging code all over your 
logic. Or would this be unviable due to application responsivity?
