Ralph identified the problem, I tracked down ''where'' the fd was being closed, and Brian figured out ''why'' (and the fix). What was happening is that a remote process was closing its stdout/stderr and therefore sending a 0-byte IOF message to mpirun. mpirun, in turn, closed the iof endpoint associated with that stream (i.e., stdout/stderr). IOF does this to handle the case where mpirun's stdin is closed -- this therefore causes the stdin on all the ORTE-started processes to have their stdin's closed as well. So the workaround here is to check that if we get a 0-byte IOF message on a sink (indicating a remote closure), and if that sink is the special stdout or stderr stream, don't actually close anything in the local process.
