Might depend.  What's the nature of the communication involved?  Lots
of data, a few simple messages, complex objects, or something else?
That is, are there constraints?

Personally, I would not use mmap.  Maybe that's because I have never
looked at it (or, apparently, needed it).  Is Queue adequate for your
needs?  (I suspect mmap is not thread-safe but I could be wrong.)
