I was thinking about an attacker, not a use case.  Think of a web
server accepting queries using iteratees internally.  This may open
door to at least DoS attacks.

And then, we use iteratees because we don't like the unpredictability
of lazy IO.  Why should iteratees be unpredictable when dealing with
Text?  Besides the memory consumption problem, there may be
performance problems if the lines are too short.

Cheers! =)
