Fix subcommand name in Django run_gunicorn error message
Log critical as critical, not exception.

This prevents weird things from happening when log.critical is called
in a non-except context.  Typically it would result in either 'None'
or the last exception being logged, neither of which is desirable.
Don't call logging functions in the signal handler.

The standard logger uses locking functions which are NOT guaranteed to
be re-entrant [1], so this could (potentially) result in deadlock or a
crash.

better logging on http parse errors

NoMoreData now inherits StopIteration and the StopIteration clause in
the workers logs the reason at debug level.
update longpoll examples

Add a longpoll example for tornado and terminate the lines we send with
a '\n'.
iremove reap_workers from signaling .
Fix using WSGI handlers with tornado worker

Without this, tornado.web.Application instances could be used as
a gunicorn application, but running a standard wsgi callback under
the tornado worker would fail.

``self.wsgi`` is the property that may be a tornado.web.Application.
The transformed application, whether originally tornado.web.Application
or a WSGI callable, should be the argument to HTTPServer.

Also, it's probably poor form to be mutating the properties of ``self``
here when a local variable suffices.
