It would be even better if we could arrange things such that
the kernel's internel clock tick rate can vary dynamically (to save
power on a laptop, for example, or to minimize cache interference in a
CPU-bound workload), without being visible to userland interfaces. It
would be better still if this could be done without excessive
complications in the drivers and other kernel modules.
