[Zope] SIGUSR2 not working in 2.6.1?

[Steve McMahon]

A bit more information. This is particular to the access log (Z2.log).

When z2.py starts the access log, it successfully saves the file_logger
instance to sys.__lg:

      lg = logger.file_logger(LOG_PATH)
      zLOG.LOG('z2', zLOG.BLATHER, 'Using access log file %s' % LOG_PATH)
sys.__lg = lg

However, when Signals.py handles SIGUSR2 and tries to recover the
file_logger instance with "getattr(sys, '__lg', None)" it can't find it
and silently fails.

I can't find this in the collector, which makes me think the platform
might be platform-specific.

Is anyone successfully using SIGUSR2 to rotate Z2.log?
