Execuse the language, but I'm reading:

	my tools suck so let's make the kernel suck!

Let's defer this discussion until next week, when I had a chance to
release my profiling tool.  I think you'll then agree that it's much
better to leave the code as is.  In fact, we should also have an
out-of-line contention handler for the read/write locks.
