Sounds good.  I'm surprised though that your change should cause such
a noticeable improvement.  It may be that the sid-side code to handle
the write queue testing/iteration is rather deficient.  (Try adding
some UNLIKELY markers to the CPU::writeback() function's while()
conditions.)

This patch has now been committed.
