Yeah -- I'm not uninterested in supporting that somehow, but on the other hand all the Mutex customizations I've seen so far have either lacked thread safety, or they depended on implementation details which would have meant they wouldn't work under e.g. JRuby either.  So I'm a little reluctant.

Out of curiosity, could you post the code in question?  It's difficult for me to see how modifying @owner could not affect the behavior of a "classic" thread.rb mutex, but then I've not seen the code in question.
