Why not run restrict mirroring and heartbeat to the same, single device (ie. 
eth1)? Seems like you want them either to both suceed, or both fail.

If you run them (mirroring & heartbeat) over separate devices you get the 
split-brain problem you mention. If you run them over the same device then 
they either both suceed or both fail.
