Also, you fail to explain why a kernel side spin futex-lock is not an
option.
I had explained that when this question came up in the last round of discussions. The queuing problem I am trying to solve stems from userspace locks. Java and databases implement their own userspace locks that do not use futex. Solving this with futex will not help the primary users of this solution.
Hope this helps.
