New description:

 We will likely someday want to do something asynchronous with
 `startConsuming`.  Perhaps a database query, or attaching to RabbitMQ, or
 whatever.  The signature is currently synchronous, so this should be
 changed and all calls to `startConsuming` converted to handle the
 resulting Deferred.

Comment (by dustin):

 This should be done for 0.9.0 so as not to introduce a breaking API change
 after that.
