IMHO a program should sleep (consume 0 CPU time and 0 energy) if there is nothing to process. This is best accomplished by not polling on a file descriptor in order to check if data has arrived. If your program must yield() there's probably something wrong with the design. I would suggest you put all the filedescriptors into a fd_set an then select(3) on the set.
Programs based on fibers can't sleep while wait data and it's not a design problem.
