Simon,

Thanks for your reply.

The FD implementation of Handles never makes a Handle with an IODeviceType
of Directory, because openFile is specified to raise an exception when
applied to a directory.
Yes, that was the only place in the Libraries' code I found that
mentions this device type (which means I haven't missed anything ;)
...
Alternatively we could give it a meaning as you suggest - newline-separated
file names seems like a reasonable interpretation.
It looks like there is no comments in the code for the definition of
IODeviceType.

I have created a ticket #4317

http://hackage.haskell.org/trac/ghc/ticket/4317

providing the code comments proposed.
