In a rush to patch a hot issue developers may deploy
a dirty codebase build. Dirty in a sense that the build
happens while there are changes to the code which are
not committed to the repository, even if local. If that
dirty build goes to production while source code gets
more changes before committing, one will never have
certainty why that production build behaves a certain
way should a problem arise.
