Comment(by viboes):

 The following prototype seems not clear to me

 {{{
 70              unlock_guard(Mutex& m_,adopt_lock_t):
 71                  m(m_)
 72              {}
 }}}

 For lock and unique lock adopt_lock_t parameter means adoption of the
 mutex was lock. For unlock_guard, adopt_lock_t will mean adoption of the
 mutex was unlock?

 I would prefer a new structure

 {{{
 struct adopt_unlock_t {}
 const adopt_unlock_t adopt_unlock={};
 unlock_guard(Mutex& m_,adopt_unlock_t):
         m(m_)
         {}
 }}}

 Maybe is just an english language question I don't master.
