Questions about scheduling

Hi!
I have a few questions about scheduling in Nagios.
- How does the scheduling queue work? From the docs it seems the
whole queue is held up as soon as a host check is necessary.
As far as I know, Nagios parallelizes checks, so my question
is if the current checking thread is held up only or if all of
the checks are stopped immediately?
- If the whole set of workers is stopped, this would mean that a
failing check would result in an immeidate host check which in
turn holds up all the queues until it is complete. Does it
really work this way?
- How much performance overhead do service dependencies generate?
I have quite a few NRPE checks and all of them depend on the
NRPE dummy check I always define. Does this stall checking by
any considerable amount?
Thansk for any help,
Tobias
