Hi Marek,

yes.

Yes, but some other functions require changes in your code (like stated
in the changes file).

All tables of v3MP and USM are protected through mutexes and if I didn't
miss anything, all reads and writes are now serialized.

The default setup surely is to listen on port 162 on all interfaces.
Listening only on 2 of 3 interfaces wasn't possible until this change.
