It's probably not exactly the same thing, and I can't speak for
performance numbers, but I found the response to this question to be
very enlightening:

The basic idea is to only access a particular resource from within a
single strand.  I'm successfully using this pattern on one of my
projects.

Depending on how flexible you need your message queues to be, you
might also take a look at "Zero MQ":
