Rack::MiniProfiler::MemoryStore::CacheCleanupThread#sleepy_run

We don't want to hit the filesystem every 10s to clean up the cache so we need to do a bit of
accounting to avoid sleeping that entire time.  We don't want to sleep for the entire period because
it means the thread will stay live in hot deployment scenarios, keeping a potentially large memory
graph from being garbage collected upon undeploy.
