Need method to force removal of handles on a queue

To delete a MQ queue there must be no open handles, ie. IPPROCS and OPPROCS must both be zero. Setting PUT(INHIBIT) and GET(INHIBIT) will disallow any further opening of the queue. Apps that have the queue open may eventually close their handles, depending on how they are coded, and when they next do a MQPUT or MQGET.
Message Channel Agents (MCAs) can have the queue open for output. After setting PUT(INHIBIT), the MCA's OPPROC handle does not go away by itself, even after several weeks. I want to be able to remove this handle without needing to stop any MQ channels or restart the queue manager, as this will have major impact on the production system.

    The qmgr already does a certain amount of tidying up of these handles when certain timers expire. We intend to add some documentation to indicate current behaviour.
