Don't.
Your IDs should not have to be in sequence, nor consecutive, nor even
in order.
If any portion of you application relies on the IDs being any
particular values, your application is broken in the first place.
You've got 2 BILLION available ID numbers. (4 billion if it's unsigned).
The fact that MySQL uses consecutive integers should be considered
more of a fluke of nature than a fact of life.
