This patchset introduces a new futex implementation called throughput-optimized (TO) futexes. It is similar to PI futexes in its calling convention, but provides better throughput than the wait-wake futexes by encouraging lock stealing and optimistic spinning. The timeout parameter, however, isn't quite working yet. More investigation will have to be done to see if this can be fixed or the timeout parameter has to be scrapped entirely.
