After these changes the code still works but I couldn't really measure any differences to the code without the extra attributes. This is on a 4p machine with 10 processes running in concurrently using mutexes and condvars with 250 threads each. This might be because either the hash function is good or very bad (i.e., hashes all futexes in the same bucket or far away). I guess the extra attributes don't hurt.
