[Boost-users] Boost.Pool: singleton_pool - thread safe for any kind of threads?

Hi All, singleton_pool documentation claims that it is thread safe. It is not clear too me if this is applied to all kinds of threads or only the ones from Boost library. For example, I am using OpenMP which is external to Boost. Would singleton_pool still be thread safe or do I need to redefine Mutex? What if I later decide to use some other kind of threads like Intel Cilk Plus or TBB? Thank you, Igor
