If I'm understanding this correctly, this will cause the monitor to silently
drop & ignore any commands issued ? Might it be better to have it print a
reply on the monitor along the lines of 'command not allowed while migration
is in progress' so people/apps interacting with the monitor understand why
it is not doing what they ask it to.
