Joe Gottman quite correctly points out in
http://svn.boost.org/trac/boost/ticket/1762
that shared_ptr should honor user definitions of BOOST_DISABLE_THREADS and
disable MT support.
Unfortunately, despite documenting quite clearly that BOOST_DISABLE_THREADS
is a user macro, Boost.Config defines it in some situations. This means that
I can't rely on this macro to reflect the user's intent, as I don't know
whether it's been set explicitly by the user, or implicitly (and incorrectly
IMO) by Boost.Config.
