This reverts commit 9d380754.

The evaluation script will start a cachedropperd subprocess
and write 'drop' to its stdin when ever it wants to drop the pagecache.
This design needs only root once either when building the artifact and
setting setuid on cachedropperd or when starting it for the first
time and setuid is not set.

add go implementation parallel walking the directory tree
