Stopping and starting the sheriff complains about needing to remove all commands before loading

[heuristicus]

While working with spot and connecting to the deputy there, sometimes when stopping and starting the sheriff this output would happen, followed by the terminal freezing:

rosrun procman_ros sheriff -l `rospack find spot_runtime_drs`/config/procman/spot.pmd
Spawn deputy!

The situations in which this happens is not clear. I observed it once when the clocks on spot and my laptop were out of sync so the sheriff was complaining and all commands on spot were in the unknown status.
