Oh, no! I'm writing my own handler.
https://github.com/fayazkhan/ses_handler/blob/master/ses_handler.py
Now I understand from here
http://docs.python.org/library/logging.html#handler-objects
that emit() calls are wrapped acquire() and release() in the handle() method.
Anyway, I read the source and found many interesting things that ought to be
mentioned in the docs.
Such as flush() should be called from close() whenever it's implemented.
(FileHandler.close() is doing it)
And how come close()/flush() isn't being called from inside a lock?
(Handler.close() calls the module level _acquireLock() and _releaseLock()s but
nothing about the instance level acquire() or release())
Or is it being locked from somewhere else?
