// Named NetSocketPosix, not NetSocketWasm, matching the precedent already set by
// wasm_thread_threadobj.cxh's UnixThread: Emscripten's socket emulation is close enough to POSIX
// (and this platform is never compiled alongside cx/platform/unix/, so there is no name collision)
// that it is simpler to keep the same class name than invent a distinct one for what is otherwise
// the same shape.
//
// send() is a concrete method on the base NetSocket now (its logic is platform-independent; only
// the syscall lives behind a shim), so this class does not override it -- bind/listen still do,
// because they touch sockaddr directly.
