It's even worse than it looks -- fuser outputs to stderr and stdout. You just get the list of processes on stdout, the rest of the line appears on stderr. It flushes both streams when "appropriate" to make the output look sane.

ompi-iof
OMPI-IOF(1) Open MPI OMPI-IOF(1)
NAME
ompi-iof, orte-iof - Displays a copy of the output streams from a process.
NOTE: ompi-iof, and orte-iof are exact synonyms for each other. Using any of the names will result in exactly identical behavior.
SYNOPSIS
ompi-iof [ options ]
Options
ompi-iof will display a copy of the indicated stdout, stderr, and/or stddiag streams from the designated process.
-pid | --pid
The pid of the mpirun executing the process whose streams are to be copied
-stdout | --stdout
Display a copy of the specified process' stdout. If no options are specified, this will act as the default
-stderr | --stderr
Display a copy of the specified process' stderr.
-stddiag | --stddiag
Display a copy of the specified process' stddiag.
-rank | --rank
The rank of the process whose output is to be copied.
DESCRIPTION
ompi-iof displays a copy of the indicated stdout, stderr, and/or stddiag streams from the designated process. At this time, a ctrl-C must
be used to terminate the program. The program will terminate cleanly, telling the associated mpirun to close the requested streams before
exiting.
