[examples] Remove broken example with no clear purpose

This example didn't compile, had no actual code changes in the last ~6
years, had no documentation explaining it's purpose, and insufficient
code comments to provide a useful example.  Removing it in favour of
fewer, but clearer, examples, that are easier to keep maintained.
