I don't know much about NFS's semantics with cache-coherency, but I take it
there isn't some sort of synchronisation operation that works on a file
descriptor and could be done instead as the vm starts and stops to avoid
having to delay the open itself? I agree with you that failing this late
could make for some rather nasty behaviour compared to the current version.

Cheers,

Chris.
