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.
