Have the threads block on a pipe read. Then dispatch the data through the pipe. The threads will awaken as a result of the arrival of the data they need to process. If the data is very large, just send a pointer through the pipe.

If specific data needs to go to specific threads you need one pipe per thread. If any thread can process any data, then all threads can block on the same pipe and they will awaken round robin.
