To fix:
9 
 
10 
o       Fix sys_idle to exit/enter kernel state and do hlt's.
11 
o       Fix scheduler decisions to reschedule. Per cpu reschedule ?
12 
o       Clean up message pass.
13 
o       Test for B stepping processors.
14 
o       Clean up processor specific/independent split.
15 
o       Document it all.        [PARTLY DONE]
16 
o       Halt other CPU's on reset/panic doesn't always work.
17

21 
o       Iterate over the slave timer requests if one is lost (keep a count per cpu)

o       Distribute IRQs (locking present just needs the 82489 to be asked
23 
        nicely).
