gcdasyncsocket address already in use

找好久找到终于找到这个

Current head of GDAAsyncUdpSocket does not (also) set SO_REUSEPORT (it just does ADDRESS, which is quite enough for TCP).

I just popped in a quick fix:

https://github.com/dirkx/CocoaAsyncSocket/commit/5ec8c83d59ecb754824f706198eb62e29961c1be

https://github.com/dirkx/CocoaAsyncSocket

and it should get fixed upstream too:

https://github.com/robbiehanson/CocoaAsyncSocket/pull/159

Thanks,

Dw.
