I don't know exactly. AFAIK the deletion of opened files is committed
after the handle is closed, i.e. it should be possible to overwrite
the old with the new version while the process is running.
However i did not test this, so it might be wrong as well. Be sure
to check this before remotely rendering the box unusable ;-)

As far as the kernel is concerned there should be no problem, over-
writing the old file always worked for me.

As an alternative, you could use a copy of ssh (maybe in /usr/local)
running on a nonstandard port while updating. You can now safely
stop the ssh service that comes with the distribution and replace
it with the new version by extracting the tarball.
