> A recent change to the management code generator caused excessive locking during the increment and decrement of counter statistics in management objects.
> This update does the following:
> 1) Change RW locks in management objects to Mutexes
> 2) Remove locking for increment and decrement operations on counters
> 3) Provide user access to the management object mutex
> 4) Add higher-level locking in the broker::Queue class to protect all counter operations as a block.
> There should now be only one lock taken out for management during the production or consumption of a message.
