Actually, me choosing virObjectLockRead over virObjectRWLockRead was
arbitrary. The reason is that my text editor can offer me completions:

virObjectLock
virObjectLockWrite
virObjectLockRead

BTW: Following your reasoning here, it should have been called
virObjectLockableLock() instead of virObjectLock() ;-)
IOW, I'm failing to see the need for 'RW' in the name you're suggesting.
