openmpi/orte/orted/orted_comm.c
Ralph Castain 728a24c8ec After considerable patience and help with debugging/testing from Tim M and Jeff S, return a completed and pretty well tested patch of the IOF to the trunk. This commit includes the previously reverted r20074, r20068, and r20064, as well as changes to fix those commits.
Basically, the remaining problem turned out to be:

1. closing stdout/stderr during orte_finalize of mpirun

2. inadvertently setting up a write event on fd = -1

3. devising a scheme to more accurately track when the stdin write event was active vs closed so it only got released once

This passed prelim MTT testing by Jeff and Tim, but should soak for awhile before migrating to 1.3.

This commit was SVN r20106.

The following SVN revision numbers were found above:
  r20064 --> open-mpi/ompi@a07660aea8
  r20068 --> open-mpi/ompi@ec930d14a9
  r20074 --> open-mpi/ompi@2940309613
