For us a worker is generic and can do whatever is needed at the time.
The way we do it is closest to: 1) request  worker or workers; 2) 
assign task to worker(s);  3) wait for result(s);

There are a number of RTOS that supply the functionality of allowing 
threads to register to be informed of specific events. QNX does this.
