1. There's no "un-synchronised" version, for use in single-threaded programs or when all (first) accesses come from the same thread.
I took the bit in the documentation saying "implementing identical behavior in a single-threaded environment" to mean they are all un-synchronised, if you compile for example using gcc without the -pthread option.
2. The "mutexed access" feature can be useful in situation other than singletons; can't something more general-purpose be provided? I use a template class Lockable<T> which grants reader/writer-exclusive access to a contained T. (Reader/writer locking could be useful here.) (It might be useful to make the mutex type a template parameter, with a sensible default; I have a few mutexes of my own, with a boost::mutex-compatible interface.)
Is any of this available publically, or documentation for it available publically? -- Frank
