Yes it was, you wrote that smart_ptr asserted because that was better
than dereferencing a null ptr so my question/point is why throw rather
than assert because locking an already locked mutex (as Peter pointed
out) is undefined behaviour. Similar results in the end so why assert
in one and throw in the other? Why not throw in shared_ptr then?
