What does "schedule coroutines directly in the main event loop" mean?

It looks like I misremembered the interface provided by txwsgi.  I 
thought it let you switch to another coroutine directly, rather than 
requiring that you yield an empty string after (the equivalent of) 
setting a flag.  This seems to be more because of WSGI constraints than 
anything else, though.
