As of r75274, patrol tokens accepted by action=patrol and generated by
list=recentchanges are no longer equal to edit tokens and are no
longer the same within a session. Instead, they are now different for
every recentchanges row (i.e. they depend on the rcid).
It may take a while for this change to be deployed to the Wikimedia
cluster, but in the meantime changing your clients to no longer depend
on the patrol token to stay the same can't hurt.
