Unlocking a mutex can never throw an exception. That doesn't make sense and our code should make sure it can't happen. Right now, provided that the system-level functions don't throw, we don't either. Locking a mutex cannot throw on Linux because we use futexes directly. A non-recursive mutex is just a futex, whereas a recursive mutex uses a mutex (a futex) to manage a lock count. However, on other platforms, due to the freelist, there can be memory allocation, which means it might throw std::bad_alloc. Not because of the freelist itself (that uses malloc and will just crash if malloc fails) but because of Q_GLOBAL_STATIC. In 5.1, the global static will be noexcept provided the type's constructor is so too (it is, in this case).
