Pawel Dziepak e083bca041 kernel: Allow threads to always finish their time slice 
Until now, when the thread has been preempted by higher priority
thread it was then placed at the end of its priority FIFO and given
a new time slice. This patch changes it allowing the thread to
complete its time slice (when the higher priority threads are done),
unless there was very little time left in which case this time is added
to the next time slice.

Apart from making the algorithm more fair this change allows to identify
CPU bound threads more easily. (Earlier they could 'hide' by being
preempted by higher priority thread and consequently never using
their whole time slice).
