Py26 test fixen.
Screw it, removing the silly broken test.
Set default timeout on the server socket
Merge branch 'master' into join
localize the timeout
Merge branch 'join' into retry
Add new retry logic to urlopen

No tests, no docs, etc, just trying to push through this to see what the
logic's like. Some things I don't like:

- it's fairly repetitive, we call increment/exhausted every time there's an
  error, and once when we have a response.
- checking the response twice, once in increment and once in is_retryable
- calling _connect_error_count from outside the class
- conflict between individual retry and total retry values causing tests to
  fail, need to nail down this behavior
- setting default timeout for a specific test instead of all of them
