This whole thing is meant for uses such as /proc and netlink
enumeration.  Speed is definitely not a prerogative of these
iterators.

For that matter, if speed was an issue then surely you would
not drop out of the RCU read lock at all while iterating.

It sounds to me like you're trying to use this interface for
something that it's simply not designed to do.
