 * 2. Pay attention to the following cases:
 *
 *    (1) Write-after-write hazard
 *        Before the connection succeeds, e1, e2 and e3 are put into the queue.
 *        Then when the connection succeeds, they are posted one by one.
 *        However, after e1 is posted, we post another event e4.
 *        I should guarantee that e4 is posted after e3.
 *
 *    (2) Read-after-write hazard
 *        Before the connection succeeds, some sticky events (e1, e2 and e3)
 *        are put into the queue.
 *        Then when the connection succeeds, they are posted one by one.
 *        However, after e1 is posted, we get a sticky event.
 *        I should guarantee that we get e3 rather than e1.
