On Dormando's prodding, here's a patch that we've been using in
production for the last week with no obvious issues. It also fixes a
minor bug that a request for a non-file or directory (eg. a fifo or a
device node) would cause the server to hang until timeout with a 500
Internal Server Error. These now return 403 Forbidden errors directly.

We're running a slightly older version of perlbal, 1.57, but this patch
should be fine against a current version of ClientHTTPBase.pm (svn 697),
albeit with -2 line offsets.
