Changes 3.3:
* Bug fixes:
  1. Inactivity timeout not triggered at correct time when occurs for first
     request after process is started.
  2. Back off timer for failed connections to daemon process group wasn't
     working correctly and no delay on reconnect attempts was being applied.
  3. Logging not appearing in Apache error log files when using daemon mode
     and have multiple virtual hosts against same server name.
  4. Eliminate logging of KeyError exception in threading module when processes
     are shutdown when using Python 2.6.5 or 3.1.2 or later. This wasn't
     indicating any real problem but was annoying all the same.
  5. Fix potential for crash when logging error message resulting from failed
     group authorisation.
  6. Fix compilation problems with Apache 2.3.6.
