CHANGE events, not quite... We can't even rely on these.

Just to mention, there's also a CHANGE event generated when
read-only flag is set for a device (this is not managed by
device-mapper of course). This one is generated even before
the actual CHANGE event that is generated when DM device is
ready to be used.
