Reliability of SOCK_DGRAM Unix-Domain sockets

Hello there,

in unix(7) of the Linux Programmer's Manual it is stated that:

(as on most Unix implementations, Unix domain datagram
sockets are always reliable and don't reorder datagrams)

I've tried hard to find some solid evidence whether or not this also applies to Linux 2.6.x - but sadly, I've failed. Could anyone please comment on Linux' behavior concerning datagram Unix-domain sockets?

Thanks,
Kai
