Hi,

I get this compiler error :

boost/thread/future.hpp", line 414: Error: Formal argument other of type boost::unique_lock<boost::mutex> in call to boost::unique_lock<boost::mutex>::operator=(boost::unique_lock<boost::mutex>) has an inaccessible copy constructor.

Because unique_lock cannot be copied. Either pass it as reference or use shared_lock.
