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.
