Fix race condition
...
- the gc finalize for an object races with the janitor.Run goroutine
- because the janitor.stop channel is created in the Run() goroutine this leads
to a data race.
- fix by creating the channel when the janitor is created

Use an RWMutex instead of a Mutex, making Get a read operation only (this slightly changes the eviction behavior: lookup doesn't completely expunge an expired item, but the janitor still will at the next cleanup.) Also, use the same RWMutex in Load and Save (thanks, Alan Shreve)
