Thanks. I wonder if it wouldn't be a good idea to have a supported way 
to keep some lua state around. For example, perhaps a globalstate table?

Setting up and tearing down a mysql connection for each call route seems 
not as nice as having a pool of mysql connections in a queue where we 
could push and pop connections. I suppose this is being done from 
different threads within Asterisk, so there would need to be locking 
involved and that might be problematic. Anyway, this sort of thing would 
be especially important for someone doing a really big dialplan where 
they want to route it by results from a sql query or where dialing 
certain extensions should provide information from the database via text 
to speech or something like that.
