Hi Ion,
Sorry, I misread that doc page. You are of course correct. What do you 
think of my suggestion to use a Windows mutex to back a boost 
interprocess named mutex? Since "abandoned Windows mutexes" are 
automatically released by Windows, we see substantially fewer hangs when 
we use Windows mutexes.

Thanks,

Mike
