// the QuotaClient interface.

// The class sets limits and defines the parameters of the systems heuristics.
// QuotaManagerImpl coordinates clients to orchestrate the collection of usage
// information, enforce quota limits, and evict stale data.
//
// The constructor and proxy() methods can be called on any thread. All other
