In mobile environment, reader optimistic spinning is still useful
because there're not many readers. In my test result at android device,
it improves application startup time about 3.8%
App startup time is most important factor for android user expriences.
So, re-enable reader optimistic spinning by this commit. And,
the later patch will make it optional feature by cmdline.
that has been done since that commit, like the handoff rework.
Why is a straight revert a sane thing at this point?
