shared doesn't automatically synchronize anything. I believe that it makes 
some guarantees about instruction ordering not being messed with by the 
compiler, but I'm not sure. I'd have to go look it up in TDPL though. 
Regardless, on a _function_, I don't think that shared does anything. D 
probably ignores it. It tends to do that with incorrect attributes. It _might_ 
do something though. I don't know.
