FWIW, that wouldn't have been my choice.  I don't know if it still does,
but it used to use userland spinlocks to achieve scalability.  Turning
your CPUs into space heaters to combat concurrency issues makes a pretty
flat graph, but probably doesn't test kernels as well as something that
did not do that.
