Some people here are uncomfortable with closing stdin, so I guess
</dev/null is safer.

Note that weirdly enough, this misbehavior from latex (waiting for
stdin in spite of \nonstopmode) is triggered by
--file-line-error-style.  I append a file which demonstrates the
problem:

      latex --file-line-error-style '\nonstopmode' '\input' /tmp/beamer.tex

hangs on stdin, while

      latex '\nonstopmode' '\input' /tmp/beamer.tex

does not.
