Wouldn't it make sense to call mythfilldatabase first and then 
optimize_mythdb.pl (since mfdb does a lot of deletes and then a lot of 
inserts--it deletes all listings data for a given source for any day 
that it updates and then puts in the whole days data).

I guess you could argue that running mfdb on a corrupt database would be 
bad, but since the table most likely to be corrupt is recordedseek 
(which isn't touched by mfdb)...

Either way, I'm sure it's better to run it at the "not perfect" time 
rather than never.  :)
