Major Description
There are remains of the (very old) blocking code in lib-http/.../HttpBase.java. This code was used with the OldFetcher to manage politeness limits. New trunk doesn't have OldFetcher anymore, so this code is useless. Furthermore, there is an actual bug here - FetcherJob forgets to set Protocol.CHECK_BLOCKING and Protocol.CHECK_ROBOTS to false, and the defaults in lib-http are set to true.
