Sean - so if I understand correctly this means that performance benefits of named locks over scoped locks (as noted in the <cflock> postings on your blog) are no longer huge?
So in summary for shared scope vars scoped locks are not going to result in the app taking a performance hit. Named locks are primarily for files or sections of code that need to single thread - correct?
