So thread A will Blocked for a very long time untill B gets to run?

NOw, I am messed by L4's schedule mechanism. It' based on static priority and timeslice.
When a very high priority thread being wakeup. It will be scheduled untill a time interrupt happen?
And does Pistachio support kernel preempt like the linux kernel 2.6?
 
Thanks a lot!---Best regardsBo Liu
