I can have a look at that, however the issue here isn't the performance
of locked sockets, but performance of the old code vs. the new code
*not using* the new feature: the real issue is how much non-users
of the locking feature will pay. This is a bit trickier to check (I need two
versions of 0MQ to do it)

The actual cost of using locked sockets has to be compared with the
cost of "doing it the old 0MQ way" using multi-plexing intermediaries
as outlined by Chuck previously. The comparison is not just performance
but also LOC and how easy each is to maintain.
