When stopping the program, it would occasionally hang. Looking at the stacktrace, it is because the listen goroutine is trying to flush, which needs the mutext, but because stop() also held the mutex, it would deadlock.

Issue: #741
When stopping the program, it would occasionally hang. Looking at the stacktrace, it is because the listen goroutine is trying to
flush(), which needs the mutex, but becausestop()also held the mutex, it would deadlock.To address this we make lock aquisition a little more granular and break out the line clearing into a separate method which grabs and then releases the mutex.
