shell script to reproduce the problem

This script reproduces PR 219216.

You need to be on an intel platform with coretemp loaded.

Every .5 seconds it prints all core temperatures. Every 5 seconds
it consumes 1 GiB from /dev/random.

If you are affected you will see access to the dev.cpu.%d.temperature
sysctls start to stutter and freeze.

To terminate the script press CTRL+C and move your mouse to feed
some entropy into the RNG.
