Yeah, I suppose there is that race possibility.

One way to fix it is to use something like file locks, such as a flock(2) on a
designated file such as $CACHE/cache_clean_interval_s.  During aging/cleanup,
hold a LOCK_EX.  During normal operation (creation of build-id subdirectories &
files), hold a LOCK_SH to permit multiple clients to work independently of one
another.
