There is an asynchronous DB insertion thread for EIT data,
and buffering which takes care of the DB inserts in the DVB
recorder (buffering is needed for ivtv too, since DB inserts
aren't the only thing that can hose an ivtv recording).
The problem is probably with the rescheduling of recordings
which can eat up a lot of resources; there is no way to avoid
the reschedule hit, it can only be made less frequent and risk
not recording a program you want to watch.
How often does the system stumble when EIT is running?
