[Haskell-cafe] Strange behavior of executeFile

[Simon Peyton-Jones]

| Anything involving sharing file descriptors between processes becomes
| similarly broken if the GHC runtime starts using a file descriptor as a
| Handle.  You're not the only one to be surprised by this behaviour, but
| unfortunately it's not trivial to work around.
|
| Simon Marlow was going to look into this problem a few months ago, but I
| don't know if he's had a chance to.

File a Trac bug report?  (If there isn't one already.)
