Comment (by thomie):

 It's not up to me to decide, but rather the 7.10 release manager's:
 bgamari or thoughtpolice.

 It's a rather big change though, and hasn't been tested much at all (!).
 Such large changes usually don't belong in a point release. But since it
 should make the GHC Windows experience much better, maybe we should make
 an exception. I just have no idea if there are any serious programs being
 compiled with GHC on Windows that might break because of this patch, and
 neither do bgamari or thoughtpolice I think, so maybe that would explain
 their hesitance to include it (correct me if I'm wrong).

 Maybe you or snoyberg could send out an email to the various mailinglists,
 asking if any Windows user is against including this patch.

 Note: last I heard, it's not even clear there will be a 7.10.3 (I'm not
 sure why not).
