+From: Kay Sievers <kay@vrfy.org>
+Subject: kmsg - do not flush partial lines when the console is busy
+
+Fragments of continuation lines are flushed to the console immediately. In
+case the console is locked the fragment must be queued up in the cont
+buffer.
+
+When the continuation line is complete and no part of it was written to the
+console up to this point, we just store the entire line as record.
+
+If the console is busy and other messages are still queued up, we should not
+try flush fragments of continuation lines, but sort them after the queued
+up messages.
+
+This keeps the console output better readable in case we receive over-long
+continuation lines we need to flush.
+
