From e200c40d7742b32aca645cda36664ea2eb9e7f56 Mon Sep 17 00:00:00 2001
From: David Rhodus <drhodus@dragonflybsd.org>
Date: Mon, 9 Aug 2004 02:59:31 +0000
Subject: [PATCH] Document that there seems to be a problem with the syncer not
 running here and that we are using a work around. If a buffer won't flush
 after 6 attempts we allow the syncer to run to process any soft update
 dependency lists.
