It is inefficient, but it is non-blocking which the AMI is not. having
a separate listen and separate send processes removes the problems
with AMI locking up on high volume Asterisk systems.

Not a problem for MySQL, that's what it does best. The astguiclient
application can do 20+ queries per second per client depending on the
application. I currently have one company with over 200 client
applications(AJAX) sending 3000-4000 queries per second to the MySQL
server, and it handles it just fine. On the client side, the load is
not very high either, even on a PIII 700MHz machine.
