For each dispatch pass, dispatchChanges.php currently picks a target wiki at random. This may cause some targets not to be updated for a long time (or, in theory, ever).

To avoid this, dispatchChanges.php should have a mode that picks the oldest (least recently updated) target wiki for each pass, trying to keep all targets up top date.

Note that it would not be a good idea to just use that mode always, since it is brittle against failure: if dispatching to a specific target fails in an unexpected way, the next pass would try that target again (since it was not updated), and again and again, never trying any other target again.
