From: Darrick J. Wong <djwong@xxxxxxxxxx>
The next patch in this series fixes various issues with the recently
added fstests process isolation scheme by running each new process in a
separate process group session. Unfortunately, the processes in the
session are created with SIGINT ignored by default because they are not
attached to the controlling terminal. Therefore, switch the kill signal
to SIGPIPE because that is usually fatal and not masked by default.
