I'm trying to say that it's not a ton of code.  lines of code are of
course not a valid way to judge complexity, and I'm not trying to say
that.  I am trying to point out that it isn't "huge" by comparing it to
other chunks of code that we all know and love.

We merge subsystems with new userspace apis that are large than this all
the time.  I'm trying to say this isn't something "unusual" at all.
