Qnet is a special piece -- there are hooks throughout the kernel
messaging code that test whether the message is local or remote and act
differently depending on the result.  The Qnet manager itself is known
to the kernel, so the kernel can redirect messages as appropriate.

If you are interested in the kernel code, you can start in ker_fastmsg.c
and follow references to COF_NETCON and net_send.  It's a complicated
system, though.
