Elaboration: the calls to quota reserve/commit/rollback were removed in 
the Pike release, so with_lockmode('update') is not called for quota 
operations, even though the reserve/commit/rollback methods are still 
there for use by old (Ocata) computes during an Ocata => Pike upgrade. 
Then, the reserve/commit/rollback methods were removed in Queens once no 
old computes could be calling them.
