You could also try using shared memory.  There's the raw
layer, like http://0pointer.de/lennart/projects/libshbuf/
or a higher layer like POSH ( http://poshmodule.sourceforge.net/ ).

I've used neither.  The letter only works on Intel (and
perhaps only Linux) because it does locking with some inline
asm.
