I have tried this variant and it doesn't work with multiple-registred classes (from diferent DLLs) even in single-threaded environment. multiset is not enough because comparison of different instances of extended_type_info of the same double-registred class still returns false. I have changed my local copy of serialization library to properly handle multiregistration, however my solution is not threadsafe in general - it just works in one particular case. If someone interested in it, I can send the patch against 1.34 version.
