I guess this is the more conservative approach, so maybe it's best. But I wonder if there's any value to expired resources _with_ validation headers in the memory cache? In that case, we're going to do a network round trip to validate anyway, so maybe an IPC round trip to the network process is also fine. Long ago, Dave Hyatt told me that the real win of the memory cache was when it could respond synchronously in the current RunLoop iteration.
