Closing an input file should be instantaneous.
It should not require any confirmation from the file computer.
It should be possible to do an instantaneous close on an
output file, too, for things like unwind protects when it doesn't
matter if data is lost.
The LOGIN operation also should not require any confirmation.
Just send it down the control connection and assume that the
flow control will assure that it reaches the other end.
This will make logging in and reading one's first file faster.
It should also not be necessary to wait for a data connection to
be flushed ("Undata-connect" in who line).
