Yeh, that would take a while.
I thought of another reason to do that also.
If you put a tablespace on an NFS mount and the remote server crashes,
it sounds like there could be a window of potential data loss. We could
guard against that by recovering the tablespace, but we don't do that
unless the local server crashes.
So having your own NFS client would allow you to tell that the link had
dropped and needed to be recovered.
