Get Estimate (doesn't require lock)

How long would I have to wait to make a request?

@param string $key  - A unique key for what we're throttling
@param int $limit   - How many are allowed
@param int $milliseconds - In this many milliseconds
@return int - the number of milliseconds before this request should be allowed
to pass
