Detailed Description

We also expose CheckingThreadSystem::Mutex, which wraps a CondvarCapableMutex to provide checked condvars and lock checking (these two must be done together, so we must wrap the mutex from which the condvar is created and use the wrapped mutex to create the condvar). This class can be used to wrap unchecked mutexes provided by other CheckingThreadSystems.
