Comment (by joehoyle):

 I recently ran into this (well, @matthue did!) with local development.
 When local site "A" wants to send a request to local site "B", it will be
 rejected, as that resolves to 127.0.0.1 via the hosts file. I think this
 is the pattern a lot of developers use with vhosts etc, so might be worth
 consideration if this goes into the next release from trunk.

 I don't know the exact security vulnerability and don't need to discuss
 that here, just wanted to point out (at least my) development process is
 affected by this change.

 Another setup I run on a prod box is 2 sites on the same machine, where
 they have "127.0.0.1 example.com" in the hosts file, which I believe again
 would mean wp_http_validate_url would brake communication between the two
 sites.
