Make the key reaper non-reentrant by sticking it on the appropriate system work queue when we queue it. This will allow it to have global state and drop locks. It should probably be non-reentrant already as it may spend a long time holding the key serial spinlock, and so multiple entrants can spend long periods of time just sitting there spinning, waiting to get the lock.
