 I am still playing with lastest iteratee and i think i found something
 strange.


 let's suppose we have a file test.hs like this:

 import Data.Iteratee
 import Data.Iteratee.IO
 import Data.Iteratee.Char

 main = fileDriver printLines /etc/passwd

 It works fine when executed via runhaskell / ghci in ghc 6.12. Compiled
 version in ghc 7
 also works, but when i am trying to execute it via runhaskell / ghci i am
 getting this error:

 iter.hs: epollControl: permission denied (Operation not permitted)

 Any ideas?


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.

 Make sure you have at least GHC 7.0.2. There were some I/O manager
 bugs in 7.0.1.

Could you please file a bug at

http://hackage.haskell.org/trac/ghc/

Give an as small reproducible test case as possible and as much
information about your system as possible.

Thanks!
