I like this approach in general, deferring to Josh on specifics.

At some point in the future, we might want to distinguish between
the different flavors of RCU -- except that there is already common
code that doesn't care which flavor of RCU is in use, as long as
some sort of RCU is present.  So make that "some point in the distant
future"...
