I'm seeming a massive slowdown in mythweb since upgrading to 0.19 that
seems to be down to time spent waiting for MySQL.

I was running an almost 0.19 build (of revision 8654) for a few weeks
and that was fine but since going to the ATrpms build of the 0.19 release
version it has slowed down hugely. Looking at the machine shows mysqld
using vast amounts of CPU before it starts returning the page.

This happens with the listings page, the recorded programs page and
the scheduled recordings page.
