Changes (by igloo):

  * milestone:  7.4.1 => 7.6.1


Comment:

 I changed my mind, having realised that this is really more of a library
 change rather than a language change.

 I made a proposal; thread "Proposal: Stop enforcing single-writer-multi-
 reader file access" starts here:
 http://www.haskell.org/pipermail/libraries/2011-October/016978.html and
 continues into November.

 However, it fizzled after Duncan counter-proposed making consistent
 locking the default, and providing a way to opt-out of locking. There was
 no clear conclusion as to which solution was preferred.
