[torqueusers] mpiexec not redirecting stdout

it may be that I am missing something, but there seems to be a problem in 
torque 2.0.0p0 (likely earlier versions too), or a problem with mpiexec. 
Consider this procedure:

schaffoe at master>qsub -l nodes=2:ppn=2 -I
schaffoe at node17>mpiexec -comm none hostname >/dev/null
schaffoe at node17>

IMHO I should not have seen anything, except if I had also used the -nostdout 
option. Could this be a bug related to / in the mpiexec patch? What can I do 
to get the output properly redirected?
