Comment (by bornlibra23):

 Is the problem I am facing due to the following statement in the
 documentation? If yes then what should I use the locks for? To protect
 against my own thread knowing that these locks are not recursive?

 The member functions of boost::upgrade_lock are not thread-safe. In
 particular, boost::upgrade_lock is intended to model the upgrade ownership
 of a Lockable object by a particular thread, and the member functions that
 release ownership of the lock state (including the destructor) must be
 called by the same thread that acquired ownership of the lock state.
