>Description:
The following bug/quirk in the tty layer has been discovered. This
issue affects processes which require tty input but are backgrounded.
This issue has been discussed with kib@ and ed@ on freebsd-stable who
confirmed the issue.
Full details are in the thread titled "pty/tty or signal strangeness,
or grep/bsdgrep bug?" here:
http://lists.freebsd.org/pipermail/freebsd-stable/2012-October/thread.html#70204
This affects any process that requires tty input; it's not specific
grep/bsdgrep.
>How-To-Repeat:
Step-by-step instructions are available:
http://lists.freebsd.org/pipermail/freebsd-stable/2012-October/070204.html

what ed@ proposes.
