Minor refactorings to mark an internal routine

Just a couple of changes to mark a routine as internal to this module (leading
underscore, helps understand what is part of the utils API and what is not),
and use of the positional argument for memcache for consistency and reduction
in line count (doing this ahead of another refactoring to keep changes
concise).
