Some of the error messages are truly awful though as things stand,

Subdividing the IOError exception won't help with
that, because all you have to go on when deciding
which exception to raise is the error code returned
by the OS. If the same error code results from a
bunch of different things, there's not much Python
can do to sort them out.
Well, the file type knows what mode it is opened in so catching these
errors is really not difficult at all.

The error messages produced for the various error
codes could perhaps be improved, but that's an
orthogonal issue.
