I haven't used libevent in a couple of years, but when I did (1.4, as  
I recall) libevent didn't create sockets for you. The expectation was  
*definitely* that you had to run WSAStartup yourself just to do  
anything with sockets.

That seems reasonable as long as libevent is just dealing with file  
descriptors that happen to be sockets.
