It looks like some are automatically skipped. t4153 automatically skips (missing TTY), and t5562 fails also but for a different reason (hang - we don't have apache2 to serve up http content).

That's fine, as long as it's wrapped up in a function in order to keep
the tests readable.
Though I suspect we may be able to just find a solution that works
everywhere, without having two different implementations. If we know we
need $count bytes for dd, we could probably just generate a file with
that many NULs in it.
Other cases don't seem to actually care that they're getting NULs, and
are just redirecting stdin from /dev/zero to get an infinite amount of
input. They could probably use "yes" for that.
