As noted in http://www.open-mpi.org/community/lists/devel/2009/08/6741.php,
we do not correctly free a dupped predefined datatype.
The fix is a bit more involving. See ticket for details.
Tested with ibm tests and mpi_test_suite (though there's two "old" failures
zero5.c and zero6.c)
Thanks to Lisandro Dalcin for bringing this up.
