Humm, in uv__udp_bind() I see:
--------------------------------------
if (bind(fd, addr, addrlen)) {
err = -errno;
goto out;
}
[...]
return 0;
out:
uv__close(handle->io_watcher.fd);
handle->io_watcher.fd = -1;
return err;
----------------------------------
So it seems that the socket gets invalidated after uv_udp_bind()
fails, and thus I cannot reuse the uv_udp_t handle again with another
address, am I right?
