If all you're wanting is atomic operators, ACE's
(http://www.cs.wustl.edu/~schmidt/ACE.html) ACE_Atomic_Op template
(http://www.dre.vanderbilt.edu/Doxygen/5.6.6/html/ace/a00029.html)
provides that. It synchronizes all arithmetic, assignment, and
comparison operators. I've used it before to do intrusive reference
counting on shared closures. A utility class that just synchronizes
operations shouldn't be too hard to write "boost" way.
