> %CPU reporting works for service and job processes, but not managed reservations.
> To reproduce the problem, create a bash script, say eatcpu.sh:
> #!/bin/bash
> while true; do for f in $(seq 1 100000); do echo 555 > /dev/null; done; done;
> and then run it viaducc:
> $DUCC_HOME/bin/viaducc eatcpu.sh
> The duccmon reservation details page always shows %CPU=0, but top shows something just under 100%
