To be clear, 500MB was about what I was seeing. Since this is all
scheduling data, then it's going to depend on a number of factors,
which may include things like the number of channels you have defined
(more channels == more possible programs to compare), the number of
recording rules, and possibly even things like the size of your
recording history (not sure if any of this makes its way into temp
tables or if it's accessed straight from the permanent tables).

Your temporary tables might be 100MB, or they might be > 1GB. The way
to tell is to monitor the /tmp folder while the scheduler is running.
Open 2 windows. In one window, run the following:

watch -n 1 du -sh /tmp

In the other, run:

mythbackend --resched

And then watch in the first window to see how large it grows compared
to the original size.
