Detailed Description

Locks down and monitors hardware for benchmarking.

This is a common base for classes that can control the specific hardware
we are running on. Its purpose is to lock the hardware into a constant
benchmarking mode for the duration of a 'with' block. e.g.:

  with hardware:
    run_benchmark()

While benchmarking, the caller must call sanity_check() frequently to verify
the hardware state has not changed.
