>Description:
	pax may sometimes stop dumping an archive on SIGINFO,
	especially when the output is a pipe.

	It seems this is because the write(2) does not restart
	the partial write after signals.

>How-To-Repeat:
	Note that the SIGINFO is raised by the tty input.
	The statistical information is what is expected,
	but it should not stop the output.

	% stty status '^T'
	% pax -w /usr/bin | cat >/dev/null
	pax: Removing leading / from absolute path names in the archive

	[[ press ^T several times ]]
