Hm, unfortunately not for me (Linux, GHC 6.8.2) ...
That's odd, because it works for me on the exact same setup. There was a similar bug in lazy bytestring's hGetContents a while back which involve it waiting for a whole chunk and not returning short reads, but from watching the strace of this code, GHC is reading byte-by-byte (which is actually pretty dumb, but functions). Can you compile both with: % ghc --make file.hs And run them with: % strace -o /tmp/trace ./file (obviously, you're running strace twice, with different binaries and output files) and send me the resulting traces? (They'll be quite big, so I don't know if you want to spam that whole list with them) Cheers AGL -- Adam Langley agl@imperialviolet.org http://www.imperialviolet.org 650-283-9641
