My concern with defaulting to 0x0200 is that it might be used on a 
platform where this is not the right value. Defaulting to 0 makes it 
easier to catch the issue and allows us to includes assertion that the 
socket option is != 0. If we build on versions of AIX and OSX that don't 
have SO_REUSEPORT defined then it would be good to get those into the 
known platform list.
