This might be a trivial problem; it's just that there are really few people
writing generators or outputing do /dev/kmsg .

Here is a sample test case the 2 different behaviours,
maybe a "flush" after the "write" would do it:

root at antec:/home/tchet# cat log
<4> log1: log1
<4> log2: log2
<4> log3: log3
<4> log4: log4
root at antec:/home/tchet# LANG=C dd if=log of=/dev/kmsg
0+1 records in
0+1 records out
60 bytes (60 B) copied, 0.000114992 s, 522 kB/s
root at antec:/home/tchet# while read level pgm msg; do echo $level $pgm $msg > /dev/kmsg; done < log
root at antec:/home/tchet# journalctl -n
...

                            <4> log2: log2
                            <4> log3: log3
                            <4> log4: log4
nov 10 20:25:20 antec log1: log1
nov 10 20:25:20 antec log2: log2
nov 10 20:25:20 antec log3: log3
nov 10 20:25:20 antec log4: log4

Ok, I don't want to test this with 20 differents MTA anyway.
