Limit req: number of cleanup calls reduced.

Doing a cleanup before every lookup seems to be too aggressive. It can lead to

The host validation was completely rewritten. The behavior for non IP literals

 - Host part is now delimited either by the first colon or by the end of string

   followed by a port number.
