remove duplicated control for flush mesage control
Motivation:
the !doneWork's control is duplicated and confused with runsSinceFlush > 2
if on the first run:the queue size is 20
donework will be set to true and not do flush due to the size<50 and
runsSinceFlush<2.
if on the second run. the queue size is 0,
donework will be reset to false and not set to true due to no new items in
queue, but the flush will be triggered due to:
if (!doneWork || runsSinceFlush > 2 || flushed.size() > 50)
now the runsSinceFlush is 2. so in actual, its function is similar with
runsSinceFlush>1.
so it is no need to keep it so that the code is confused and duplicated.
Modifications:
remove it
Result:
after remove it, it will more clear and no confused.
