what is currently the thread safety for Teuchos::RCP? Is it as for
boost::shared_ptr? So smething like "boost::shared_ptr<> offers a
certain level of thread safety. The reference count is manipulated in
a thread safe manner (unless you configure boost to disable threading

This would include things like setting parameters with an RCP<ParameterList>; the different solvers shouldn't share those.  We have a plan for making RCP thread safe, but haven't had time to work on this yet.
