help messages so that users only see the message once instead of N times when their MPI app crashes. Note that there is a tradeoff here -- we now call malloc in this particular "show the error" code path. This shouldn't usually be a problem, because the errors typically displayed through this mechanism are MPI API argument problems (e.g., sending a negative count to MPI_SEND), and not memory errors. But such API argument errors could be a consequence of of a prior memory error, so there's a nonzero chance that the error failure will fail to print because malloc failed. In this case, the user can disable help message aggregation (via the orte_base_want_aggregate MCA parameter) and we'll fall back to the no-malloc code path (but without aggregation). Note that we won't aggregate before MPI_INIT or after MPI_FINALIZE. So if you call an MPI function before MPI_INIT / after MPI_FINALIZE, you'll still see the error message N times. Nothing we can do about that; we need ORTE to do the aggregation properly (which is obviously unavailable before MPI_INIT / after MPI_FINALIZE). This commit was SVN r19611.
