        # A full build of llvm, clang, lld, and lldb takes about 250MB
        # of ccache space. There's not much reason to have more than this,
        # because we usually won't need to save cache entries from older
        # builds.  Also, there is an overall 10GB cache limit, and each
        # run creates a new cache entry so we want to ensure that we have
        # enough cache space for all the tests to run at once and still
        # fit under the 10 GB limit.
