I have a couple of cpu-bound performance tests that I just ran with and
without the patch.  Everything is ran with n=1 until volatile issue is
sorted out but so far I am not seeing any performance
improvement...believe me I would like nothing more than to report
otherwise.  Also my tests maybe don't stress the signal code much.  I
observed both the running time measured from the client and the weighted
average cpu load on the server.

Maybe it make a difference with high user load.
