Round-robin among processes with equal priority and that are eligible for CPU
service can only occurs when the quantum time is passing away. The round-robin
actually occurs on rsched calls. Thus, the procedure ready must refuse context
switching for processes with equal priority and that are eligible for CPU 
service. Otherwise, system calls like resume, signal, and that use ready can
give a context switching. For example, a process that signals an other one 
with the same priority will lost the CPU for a while.
