// With this change the stop effector will wait for Location to provision so it can terminate
// the machine, if a provisioning request is in-progress.
//
// The ProvisionMachineTask stores transient internal state in PROVISIONING_TASK_STATE and
// PROVISIONED_MACHINE: it records when the provisioning is running and when done; and it
// records the final machine. We record the machine in the internal sensor (rather than
// just relying on getLocations) because the latter is set much later in the start()
// process.
//
// This code is a big improvement (previously there was a several-minute window in some
// clouds where a call to stop() would leave the machine running).
//
// However, there are still races. If the start() code has not yet reached the call to
// location.obtain() then we won't wait, and the start() call won't know to abort. It's
// fiddly to get that right, because we need to cope with restart() - so we mustn't leave
// any state behind that will interfere with subsequent sequential calls to start().
// There is some attempt to handle it by ProvisionMachineTask checking if the expectedState
// is stopping/stopped.
