Built-in concurrent/thread-safe map

I was just watching Andrews presentation (http://osdc.blip.tv/file/4432146/) and his
workaround for thread-safe maps. Yes, it's a way to use a mutex for a whole map. But why
don't you provide built-in maps that are already thread-safe? 

That way you have much more control over how the thread-safeness is guaranteed, e.g. by
using locks per block/segment instead of locking the whole map.

Hm ok, thanks.  Maybe I'm still too much into Java ;)
