[Twisted-Python] A nit on "Generalization of Deferred Execution in Python"

[Tommi Virtanen]

	"It is suggested that methods which must perform long-running
	calculations or communication with a remote host may return a
	Deferred."

	That's a horribly misleading paragraph. What you probably want
	to say is that you recommend such things to return a Deferred
	-- I currently read that such that functions should sometimes
	return Deferreds and sometimes real results, and that is very
	confusing. That's why there are defer.succeed() and
	defer.fail().
