Jeff I'd like to start some small diffs that resemble the one
included.. 
This one changes shched_clock to use a thread.
I'd also like to commit a change to make KEF_IDLEKSE
to TDF_IDLETHREAD as you suggested.

Here I'm running with a file sys/ksevar.h that has 
teh kse structure in it.
eventually it would be in teh scheduler .c file
so I am not going to commit that change yet..

comments?
