Hi Duncan,

I tried to place a "length text `seq`" before the mapM_ writeExport to force
the process output to be read but the result was even worst (only one line
printed). Apparently withtout the `evaluate` function it causes more
troubles than it solves.

The example you provided is really helpful. I learned a lot reading it.

Thanks,

Olivier.
