Looks like its something similar to Pylons web framework. While
generally globals vars are indeed bad, in this case they are
specifically provided by framework to be used this way.
They are 'thread-local' rather than global, and usually cause no harm,
since framework guarantees that these instances are bound to context
of this particular http request.
