Hello Roland,

one guy (Terry D. Dontje) already answered in the devel_at_[hidden] mailing list:
http://www.open-mpi.org/community/lists/devel/2011/11/10011.php

As I've understood him, he thinks the same. Now I'm trying to do what he wrote and answer soon...
Thanks for your estimation!

Best regards,
Lukas
