No, I am not sure. But this SO reply seems to suggest

http://stackoverflow.com/questions/14388706/socket-options-so-reuseaddr-and-so-reuseport-how-do-they-differ-do-they-mean-t/14388707#14388707

But: there are actually 2 things required (which Linux does):

a) able to share sockets (without communicating a socket descriptor over 
some channel)
b) have the kernel load-balance incoming connections over all processes 
listening

E.g. FreeBSD does only a) currently, not b)

Interesting! But that's not what Linux does, as it requires to 
communicate  WSAPROTOCOL_INFO over to other processes.

AND: it's not clear from the MS docs if the Win kernel will actually 
load-balance incoming connections.
