Hi!

> Are message queues (msgrcv, msgsnd) thread safe in linux pthreads?

Yes, they are.

However, notice that you might be suject to race condition if, for 
instance, two threads try to pick-up the same message type at about the 
same time.

But from your description, that kind of problem doesn't seem to occur, 
since each thread uses unique message type.
