This, yes, as usual :) > And HTL of course has its own rwlocks implementation.

Well, at some point we'll probably want to just do like nptl and simply #define __libc_rwlock pthread_rwlock, so it's probably not worth spending time on making a separate __libc_rwlock implementation, and rather spend it on making pthread_rwlock use gsync, like was done for pthread_mutex and sem, and then we can just #define __libc_rwlock pthread_rwlock.
