I wasn't aware that this function was so leathal. I use it constantly

It isn't that "lethal" usually. It's only because he was using it on
an infinite stream that it hurt so much... If you use it on a normal
stdin or a hGetContents on a file it will be fine (though you will
lose the advantage of its laziness, for example constant memory
treatment).
Nevertheless, length is a function you should rarely use.
Amen.
(I believe the Wiki mentions this concept somewhere... Maybe we should
rename it unsafeLength? No, OK, how about... um... slowLength?)
