/me prays we won't go back to our *old* export failover proposal (about 
two years ago) :) ...

Anyway, re-export is part of the required steps that take-over server 
needs to do. It, however, doesn't handle lockd grace period so we will 
have the possibility that other client will steal the locks away. That's 
why Bruce and I are working on the second "resume" patch at this moment.
