Wow. That's super cool. I have backed off my implementation to another  
approach which can do without the interprocess stuff, but at a great  
performance cost. I can make progress on my work without interprocess  
for a few weeks. I am far from expert in either boost or FreeBSD, but  
if there is anything I can do to help please let me know.
