How I can set the quantum? Is km_quantum from kse_mailbox the right
place? I did not get any upcall when I set it.

Also found, that "ps" and "top" do not show CPU utilization at least
when one KSE with mailbox exists (5.1-RELEASE): 
1036  p4  R+     0:00.00 ./kt

Process 1036 runs "printf" in loop.

Thanks,
Sergey.
