# Redis matters even though few tests touch it directly. settings.py falls back
# to redis://localhost:6379/1 when REDIS_URL is unset, and on a machine running
# several projects that port belongs to whichever one started first — so the
# suite would connect to a stranger's Redis and write into its database.
# CACHES sets IGNORE_EXCEPTIONS, so this fails silently rather than loudly:
# cache-backed behaviour (LastActivityMiddleware's throttle, rate limiting) just
# quietly does the wrong thing.
