David Howells c69e8d9c01 CRED: Use RCU to access another task's creds and to release a task's own creds 
Use RCU to access another task's creds and to release a task's own creds.
This means that it will be possible for the credentials of a task to be
replaced without another task (a) requiring a full lock to read them, and (b)
seeing deallocated memory.
