What would you like to see, a repeat of the SUMMARY or DESCRIPTION lines 
added to the corresponding commit messages (if so, which)? 

Other than that, I don't know what else to say about them; if their absence
wasn't breaking Tornado, I would not have picked either of these particular
modules to submit. Neither one has much use yet outside of Tornado (found no
other users of abc, while singledispatch is also used by rpy (python interface
to R).
