It's cool to see these interesting ideas for using some of the code
I've been working on for the last couple of years.  However, it seems
to me that a better design would avoid the use of shm_mq.  Instead of
having the guy who asks the question create a DSM, have the guy who
sends back the answer create it.  Then, he can just make the DSM big
enough to store the entire string.  I think that's going to be a lot
more robust than what you have here.
