Initializing and locking a mutex (or spinlock, or other primitive) is a
not too unusual pattern, often used when inserting an object into a
hash table or other lookup data structure.  So supporting it without
creating pointless wrapper functions would be really useful.  One thing
that would be nice to have and probably help here is to have lock
initializers that create the lock in a held state.
