Janne, as I know you were interested in that feature, could you look at my
patch if you have some time?

Here's a message on the mailing list that provides some benchmarks as well as
one possible interface for how one could use it:

http://gcc.gnu.org/ml/fortran/2005-11/msg00474.html

Actually, I'm feeling a bit tired of banging at the IO library for the moment,
so I'll assign this bug to myself.
