<p>How is this different from saying MPI_REQUEST_FREE was a mistake. The behavior of an application that uses this call is undefined.<br>
<br>
Of course we could add MPI_NO_REQUEST_FREE as an MPI_Init time assertion and say that any MPI implementation optimization that create the problems Erez describes are only valid when the application has asserted MPI_NO_REQUEST_FREE. <br>
