Re: Shared memory IPC using NIO memory-mapped files -- anyone done this?

IIRC Win32 short-circuits the TCP/IP stack (somewhat severely, such that
tools like Wireshark/Ethereal can't see the localhost-addressed packets),
which yields a pretty significant perf boost, but it's still not the same as
using pipes or something similar.

MacOS I have no idea.
