commit 9d3a0de makes slaves expire as they would do on the master with much shorter timeouts. But it introduces another problem: When we close a connection, on master server the connection became CLOSE_WAIT/TIME_WAIT, it was synced to slaves, but if master is finished within it's timeouts (CLOSE), it will not be synced to slaves. Then slaves will be kept on CLOSE_WAIT/TIME_WAIT until timeout reaches. Thus we should also sync with CLOSE.
