could you explain this please?
I use something like that myself, as a workaround, but I don't see how that is 
a desired solution.
why would you hash to access something that should be one word in size?

in makes sense if you try to avoid the pthread mutex memory overhead, but if 
you put effort into it wouldn't it make more sense to replicate exactly what 
pthreads does inside boost and avoid the overhead and the hashing?
