Hello,

I've noticed that term/users.c calls set_atime/mtime for each and
every io_write/read performed on a tty. This means for instance that
each keypress on the console or via ssh will dirty the tty node and
eventually lead to a disk write for the underlying node a few seconds
later.

Do we really need to update mtime/atime for ttys?  It seems overkill to
me.
