Apologies, I won't have time to look at this for a few days. However, could you try a test using the functions from Data.Iteratee.IO.Posix directly? That would help narrow down the issue. I suspect it's either a bug in ghc's IO, or the semantics of some IO functions changed without my noticing. John L.
