If we are going to read a large object from network try to make it likely that it will start at c->querybuf boundary so that we can optimize object creation avoiding a large copy of data. But only when the data we have not parsed is less than or equal to ll+2. If the data length is greater than ll+2, trimming querybuf is just a waste of time, because at this time the querybuf contains not only our bulk. It's easy to reproduce the that: Time1: call `client pause 10000` on slave. Time2: redis-benchmark -t set -r 10000 -d 33000 -n 10000. Then slave hung after 10 seconds.
