The tricks I am going to describe allow you to create unique gmail addresses that still hit your existing gmail inbox, without actually making new gmail accounts.

Consider these 2 examples:
- Between 1 and 100 UPDATE queries are constantly running on the master in parallel. If the slave IO is only fast enough to handle 50 of them without lagging, as soon as 51 start running, the slaves starts to lag.
- A more common problem is when one query takes an hour to run (let's say, it's an UPDATE with a
