          Hardware: x86_64

Conceptually, a sleep is not a side effect and can be implemented with
unoptimized assembly code, e.g. running n noops instructions. Since we are
using the kernel implementation for precision sleep and it provides a well
documented behaviour we should trust it and fake pure it.
