Probably a stupid question:

Is there a possibility of trouble if the optimize job were to run at  
the same time as mythfilldatabase?

I'm assuming the two operations could "get along" but it might cause  
a timeout on MFDB because some of the optimize steps can take many  

I'm following the "suggested next" so I can't predict the precise  
time MFDB will run, so I've just been running the optimize manually  
every few days after checking.

I guess I could create a script called from a cron job that checked  
if MFDB was running before starting to optimize but even then it  
could start immediately after the optimize started.

I suspect I'm just being too paranoid, but...
