You are perfectly right.

So you should try to avoid heavy ref counting (i.e focusing / defocusing 
ref counted stuff, including Strings) in multithreaded code. Problem: 
the programmer can't easily see where  focusing / defocusing is done.

OTOH, ref counted objects can reduce the programming effort when 
thread-local instances are necessary.

Depreciating ref counted objects for multithred-performance means to 
depreciate Strings as well. ;-)
