Folks, I'm looking at the code for singleton_pool, and I can't *quite* convince myself that it's completely thread safe and guaranteed to do what it says, the code in question is in boost/pool/detail/singleton.hpp which is a deceptively clever/simple singleton implementation. I haven't been able to break it in practice, but would a sufficiently clever compiler be able to optimize away the call create_object.do_nothing(); and therefore not instantiate the object prior to main()? Thanks in advance, John.
