What about receiving order, does same principles apply?

For example, i have rsyslog installed on my machine with defautl
configuration. Only one output to file is created.

If i do the following:
cat <path_to_file_1GB> | nc localhost 514
Or, i just create a TCP socket (in python for example,one thread only),
connect to (localhost, 514), read the 1GB file and send line-by-line.

I see that syslog save all messages to destination file, no message is lost
but order is mixed. 

I'm aware of all refactoring that was done (<!-- m --><a class="postlink"

post (<!-- m --><a class="postlink"

By default, both queues are set to one worker maximum. [b:1jvmrzyo]The
reason is that this is sufficient for many systems and it can not lead to
message reordering[/b:1jvmrzyo]. If multiple workers are concurrently
active, messages will obviously be reordered, as the order now, among
others, depends on thread scheduling order.

Is post outdated or i'm confused, there is a good chance  latter is true
since i don't have a lot of experience with rsyslog :)

Is there any way to configure rsyslog to preserve message order that it
receives?
