Had group discussion about this on the weekly call. The decision was that we should pass the real error code to the back-end exception handler because it's pretty useless to pass MPI_ERR_IN_STATUS to the back-end exception handler (because exception handlers don't have access to the request or the status - this has potential issues for fault tolerance kinds of scenarios). So in TESTALL, TESTSOME, WAITALL, and WAITSOME, we examine the error code and if it's not MPI_SUCCESS, return MPI_ERR_IN_STATUS. This commit was SVN r12389.
