That's *heavily* OS-dependent. Not all implementations of AF_LOCAL
sockets work the same.

True. But don't forget either that just because one implementation of
AF_LOCAL actually is reliable doesn't mean that they all are. (Though
if AF_LOCAL sockets are reliable, they should be SOCK_RDM rather than
SOCK_DGRAM, I think.)
