That's a somewhat vague request. If you have specific ideas/suggestions 
here feel free to raise them on the concurrency-interest at 
mailing list where Doug Lea and the JSR-166 EG will see them (along with 
a large chunk of the community interested in concurrent collections).

Again can you be more specific? Read-write locks sound theoretically 
useful for some collection operations but the devil is in the details. 
Unlike synchronized collections you can't necessarily just use a wrapper.
