Management of the MCB is important to allow timely access to the MCB
by all devices. The MCB software should manage the bus in a way that
will maximize the throughput for all devices, and will not starve out
those devices that need service that may be of lower priority. It
will also recognize when a device is unavailable, and will not waste
the bus bandwidth repeatedly reading a dead device. Currently, this
is one of the more fundamental flaws in the way the M&C software uses
the MCB.
