time-delayed-standby.patch (application/octet-stream) patch

While I was out at the MySQL conference last week, I heard that one of
the forthcoming MySQL features is "time-delayed replication":

http://forge.mysql.com/worklog/task.php?id=344

That is, a standby configured such that replay lags a prescribed
amount of time behind the master.

This seemed easy to implement, so I did.  Patch (for 9.2, obviously) attached.
