I cannot help you with your question more than pointing you to
http://bugs.darcs.net/issue391
where Simon Marlow explains how to avoid "IO.bracket".
I'm using Control.Exception's bracket. Also, following Jeremy's advice, I replaced the last line of rechf2 with return $! rech r $ lines f and indeed it works. I don't understand why it doesn't without the ! The documentation for hGetContents says the items are read on demand. the function rech needs the strings so they should be read on demand. This confuses me :(
