Review comment:
I this case let us set 'limitCnt'=0 as soon as we have first node's portion
that fulfills our limit. But arrived data from 2nd node still makes enqueue()
to be called one more time. For 'limitCnt' =0 the first condition will fire as
if it is no-limit case (limit<=0 is treated as no limit) what is not good
specially here. So we need to add kind a 'limitReached' flag, set it in 'else'
block and check at the method entry.
