Comment (by vvv):

 I have some news. First, there is a
 [http://hpaste.org/fastcgi/hpaste.fcgi/view?id=9447#a9488 proof of
 concept] module manifesting this weird behaviour. Second, the problem
 seems to be caused by using `Lazy.ByteString` for HTTP response body (see
 `getHTTP` function in Distribution.Client.!HttpUtils). Once it's replaced
 with strict !ByteString, the [POC] module starts downloading complete
 files.

 Please see my [http://trac.haskell.org/http/ticket/8#comment:6 comment to
 HTTP ticket#8] and consider replacing Lazy.!ByteString's with strict ones
 where appropriate (!HttpUtils.hs, Fetch.hs, ...?).
