Subject: [PATCH] process: wait longer 5->30s on hard shutdown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In cases where virProcessKillPainfully already reailizes that
SIGTERM wasn't enough we are partially on a bad path already.
Maybe the system is overloaded or having serious trouble to free and
reap resources in time.

In those case give the SIGKILL that was sent after 10 seconds some more
time to take effect if force was set (only then we are falling back to
SIGKILL anyway).
