advantages:
- a context can not consume more than the _allowed_
amount of cpu resources (configured as token bucket)
- you can 'freeze' a context at any time with the
sched_pause flag
disadvantages:
- the scheduling overhead is larger than on a normal
system, or with the sched_prio config
- processes might run out of tokens at unfortunate
moments (e.g. when waiting for I/O and such)
