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.
