| * While this is the javascript implementation, it does not actually call any | ||

| * post, just like the corresponding native implementations are. Since the | ||
| * javascript has perfectly good support for HTTP, we don't really need the | ||
| * overhead of going to native. In fact, you could even argue that we don't | ||
| * really need a wrapper here since the default implementation is easy enough | ||
| * to use, but abstracting out the implementation makes it consistent with | ||
| * native code, and simultaneously makes it easier for us to change the library | ||
| * if we switch to a newer and cooler library (websockets? pub/sub? capnproto?). | ||
