I haven't looked at this very carefully yet. Maybe someone can confirm what I'm seeing? If I try to "mpirun `pwd`", the job should
fail (since I'm launching a directory rather than an executable). With v1.7, however, the return status is 0. (The error message
also suggests some confusion.)

My experiment is to run

     mpirun `pwd`
     echo status is $status

Here is v1.7:

     Open MPI tried to fork a new process via the "execve" system call but
     failed. This is an unusual error because Open MPI checks many things
     before attempting to launch a child process. This error may be
     indicative of another problem on the target host. Your job will now

       Local host: /workspace/eugene/v1.7-testing
       Application name: Permission denied
     status is 0

Here is v1.6:

     mpirun noticed that the job aborted, but has no info as to the process
     that caused that situation.
     status is 1
