To be fair the code in question was written many years ago - before anyone I know had heard of zeromq (it existed but wasn't known). it would be possible to optimize the mutexs out I'm sure - but the big problem wasn't speed it was complexity of code that I now maintain. Since local sockets are easier and faster I'm safe deleting the more complex code that should have never been written.
