I get that bit, but my question is essentially: what triggers the
errback? If the LineReceiver gets a line that's too long, *how* do I
errback on the deferred? Should the protocol hold the deferred? The
factory? Whatever creates the factory? Does it matter? ("No" would be
a fine answer to the last question, my whole problem is that I don't
really know the "Twisted" way to approach this, or if there even is
one.)
(I would ask: do I even need a factory? But the fact is that I do,
since all of the useful mixins and base classes rely on one being
present.)
