-// Lifetime for this class is maintained by posted "tasks" which ref count it and by MainThreadStorageQuotaCallbacks.
-// Either a task finishing or the MainThreadStorageQuotaCallbacks being deleted may release the last ref on WorkerStorageQuotaCallbacksBridge.

-// A typical flow for queryUsageAndQuota would look like this:
-// Bridge::postQueryUsageAndQuotaToMainThread() on WorkerThread
-//  --> Bridge::queryUsageAndQuotaOnMainThread() is called on MainThread
-//      This makes an IPC with a MainThreadStorageQuotaCallbacks instance
-//     [actual operation is down in the browser]
-//  --> MainThreadStorageQuotaCallbacks::didXxx is called on MainThread
-//  --> Bridge::didXxxOnMainThread is called on MainThread
-//  --> Bridge::didXxxOnWorkerThread is called on WorkerThread
-//      This calls the original callbacks (m_callbacksOnWorkerThread).
