http authorization caching

[Brad Schick]

Does mercurial have any way to cache basic http authorization? I'm
setting up a repo that is private, so even pulls is restricted, and
we're finding it a hassle to type username and password so often. Even
just stashing the username and hashed password in a file would be fine.

I realize ssh has caching with ssh-agent, but we aren't able to create
multiple ssh accounts on the server.
