Why not add an error handler yourself for these Deferreds?

It is possible to get a function called for all unhandled errors by
adding a log observer
(http://twistedmatrix.com/documents/current/core/howto/logging.html#auto5) but this logging only happens on garbage collection of the Deferred, which means it can be delayed indefinitely in some cases.
