Comment (by nomeata):

 I was under the impression that people tend to think badly about lazy IO
 these days, so I’m not sure if it makes sense to make
 `getDirectoryContents` lazy. Unless of course most people expect it to be.

 I think a way forward is to make `getDirectoryContents` non-lazy, but not
 blowing the stack (if that still is a problem on 7.8), and alternatively
 think about an interface for people who need more control over that. Maybe
 http://hackage.haskell.org/package/filesystem-conduit-1.0.0.2/docs/Data-
 Conduit-Filesystem.html is already that solution.
