> The code in Qpid Dispatch Router currently does mobile address synchronization between
routers in the Python router module.  This has a couple of drawbacks in cases where there
are large numbers of addresses:
>  * The address strings are stored twice:  once in the main address lookup hash table
and again in the Python mobile address module.
>  * Address lookup on the Python side is inefficient and has been a bottleneck (improved
recently by a patch from Gordon Sim).
>  * Python processing is single threaded.  A large mobile address update can cause delays
in processing management requests and link-state topology maintenance.
> The python router module was intended to be an on-the-side control-plane moduel that
was not in the critical path for any performance-related activities.  With large numbers
of addresses in a network, synchronizing address locations becomes performance-related.
> To address these issues, mobile address synchronization can be moved into a core module
where it can use and share the same address table that is used by the router core for make
high speed routing decisions.  In the process, it will leave the python modules alone to
process management requests and topology maintenance uninterrupted.
