ハAscheduling algorithm in which processes are activated in a fixed cyclic 
order.  Those which cannot proceed because they are waiting for some event 
(e.g. termination of a child process or an input/output operation) simply 
return control to the scheduler.  The virtue of round-robin scheduling is 
its simplicity - only the processes themselves need to know what they are 
waiting for or how to tell if it has happened.  However, if a process goes 
back to sleep just before the event for which it is waiting occurs then the 
event will not get handled until all the other processes have been 
activated.

もともとの意味がなかなか面白い！

Round robin. [Perhaps F. round round + ruban ribbon.]
        (a) A written petition, memorial, remonstrance, protest,
            etc., the signatures to which are made in a circle so
            as not to indicate who signed first. ``No round
            robins signed by the whole main deck of the Academy
	or the Porch.'' --De Quincey.
