limit is reached?

After a message is deleted from the mbox, can this UID ever be reissued to a new message or is that UID retired? What about after the 2 billion

The limit is 4 billion. There is code that if the UIDs reach that high, a new UIDVALIDITY value is given (to invalidate client caches) and all UIDs are renumbered to start from 1, but apparently that code doesn't work.
