   Actually, I imagine the user will notice:

	   % cat old-file
    {*yawn*  Gosh the machine is slow today...}

They certainly will. EXEC 8 does exactly that, rolling out old files
to tape and rolling them back in when referenced. One of the first
things I learned to do was assign all my files with the nowait option
whenever I logged on. Gee, Chris, think of all the fun you missed :-)

I know of at least one company who makes an NFS file server with real
disks staged and destaged to optical disk. In that case, while the I/O
is certainly slower, at least it's faster than waiting for an operator
to find and mount the tape.
