This is client-server based implementation of multiple threads.
It is implemented using msgqueues and shared memory.
Client sends request to server using msgqueue.
for every request server creates a thread which then separately handles the client.
Thread invokes a processing client and gets the result using shared memory.
It then returns the result to client using msgqueue.
Thread is detached from main-thread.
