It doesn't seem very abusable... Though of a server accepts enough remote
connections and uses input() and swaps out stdin after remote uses up fds
with connections...  That's a lot of circumstances at once. Rare
application.

We ran into it with an interactive program controlling a bunch of things so
it had lots of fds open when a tty stdin was swapped in for input.
