Mike Hello
Correct. OFFSCHED has a real time facet that puts it in the SMP real
time system arena. it has other facets such as security and
monitoring. If you take a look at OFFSCHED-RTOP and OFFSCHED-SECURED
you will see that I can actually get information and change a system
properties (very pool implementation so far, i am a bit tired...)
even if this kernel is not **accessible**.
