--- Comment #12 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-11-10 22:53:46 UTC --- Note that the IO block escapes and thus cannot be coalesced with others in the same function. I had a frontend patch to re-use the same IO struct across multiple calls but that was rejected on the grounds of future implementation of async IO.
