Fast way to send message between 2 child processes? (using a file is too slow?)

Probably.

The vast majority of the stuff that I write that needs IPC is on 
Windows, so neither unix domain sockets nor shm is really available 
(unless cygwin is able to work its magic).

I suppose could probably muck around with some win32 extensions and have 
some special casing *nix/windows, but I'll probably end up sticking with 
async (or unix domain) sockets unless I /really/ need speed.  It is good 
to know that shm is around though.
