I don't buy the --disable-smp argument. The mutex (or the type of
serialization done by the CPU primitive) is also there to protect
against getting timesliced at an inopportune point in the update
sequence. Otherwise another dispatchable unit can progress merrily
through the same update sequence and result in an inconsistent state
once the first dispatchable unit gets the CPU back and finishes the
sequence.
