[Mpi-forum] MPI_WAIT/MPI_TEST and generalized, I/O, and NBC requests

[Bronis R. de Supinski]

Fab:

Hmm. I don't know if is a ticket 0 change (probably
not) but it definitely is an errata that we should
fix before we relaese MPI-3.0. Can you write up a
ticket? I'm happy to look over the text. I hope
this can get on the March agenda since it should...

Are generalized, I/O, and NBC requests not completed the same way?  Are users required to free such requests explicitly after they complete using MPI_REQUEST_FREE?
