My understanding of English is that
Any other type of request is and the request handle is set to MPI_REQUEST_NULL. is a broken sentence.
The Erratum should only correct the wrong implementation of ticket 321. It has nothing to do with any discussion of whether the current description of MPI_WAIT (including the missing word "deallocated") is perfect. I would say, that any further change of the wording would be another discussion for the next version of the standard, or for another erratum. Rolf ----- Original Message -----

Just saw this, but not sure I agree with the correction. What actually happens is implementation dependent, but the handle the user sees is indeed MPI_REQUEST_NULL.

Dear pt-2-pt WG and all,
In the description of MPI_WAIT, MPI-3.1 page 53 line 24-25 and MPI-3.0 page 53 line 27-28 reads
Any other type of request is and the request handle is set to MPI_REQUEST_NULL.
but it should read
Any other type of request is deallocated and the request handle is set to MPI_REQUEST_NULL.
This corrected text was voted into MPI-3.0 through ticket 321. The missing "deallocated" is a "typo" probably during the implementation of this ticket before MPI-3.0 was published.
Ticket 321: https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/321 and https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/321/ticket321... page 54, lines 14-18.
This is a request for an erratum for MPI-3.1, which also applies to MPI-3.0.
Best regards Rolf
