I have never used POSIX message queues, and that would only give me -R
in any case, since I would still either need shared memory or a new
positioning algorithm for -c.
Instead, I would open a lock file and use that to co-ordinate which PV
is the "first" one and where the "top" Y co-ordinate is. I might not
even need mmap() at all. So long as I'm using lock files for the
terminal anyway, it seems that I might as well also use them for the
rest of -c and -R.
So this is why I think it would be easier to use lock files and/or mmap
than trying to use message queues.
