I took a look at that (especially the posix_ipc at
http://semanchuk.com/philip/posix_ipc/).  I am hoping
not to plug something underneath the Python VM; I
would rather use a socket, or use signals.  If I were
to use a C library, I imagine I would just go with a
thin layer on top of pthread_*, but I think I will
prefer something which uses system calls and is
bundled with Python, slow as that approach may be.
