AFAICS mt.changes is the same channel as machineUnitsChanges, which
there's no reason to close ever IMO (although I see that it is closed in
fact - i'd remove that).
I suggest putting machineUnitsChanges inside the firewaller type, so
this line would be:
case mt.firewaller.machineUnitsChanges <- ...

which makes the mux logic more clear, i think.
