The schedule list is stored in memory on the master backend.
Whenever something needs this info, it asks the scheduler thread.
The scheduler thread only regenerates the list when it has to
rather than every time info is requested as it did a few versions
back. A RecordChanged event happens whenever a rule changes, a
recording starts, the listings change, a slave backend connects
or disconnects and maybe some others. Whenever this happens
you would see the "Found changes in the todo list" message from
the master.

Deleting a recorded file doesn't trigger a RecordChanged. In
theory, you might choose Duplicate Location: Current Recs and
and delete a file minutes before another showing of the same
episode that you do want to to record again even though you
just finished watching it (I'm tryin' here ;-). This is so
obscure that it's not worth running the scheduler for every
delete.
