/*
[WARNING] On Android, the libuv documentation of "UV_UDP_REUSEADDR" is true, i.e. only the socket that binds later on the same port will be triggered the recv callback; however on Windows, experiment shows that the exact reverse is true instead.
It's feasible to use a same socket instance for both receiving and sending in different threads, however not knowing the exact thread-safety concerns for "uv_udp_send/uv_udp_try_send" & "uv recv callback" stops me from doing so, I'd prefer to stick to using different socket instances in different threads.
