When call_once returns it is guaranteed that foo has run to completion exactly once. If two thread run it in parallel one of them will block while the other runs foo.
Ok, I ask again specifically: Does boost::once ensure that called function will be performed "atomically" rather than "mutually excluded"? I mean "atomic" foo performance but not "mutex'ed".
