TCP (POSIX) async send/recv working. Other changes.
Transport-level pipe initialization is now sepearate and explicit.
The POSIX send/recv logic still uses threads under the hood, but
makes use of the AIO framework for send/recv. This is a key stepping
stone towards enabling poll() or similar async I/O approaches.
