The latest code  looks a bit similar to the old  [linux] big-reader-locks  hack
(which got dropped for good many eons ago and with which i deny any involvement
with, such as having authored it. [oh, did i say that out loud? crap.]), imple-
mented cleanly and properly.     -- Ingo Molnar <20090428124033.GA1655 at elte.hu>
