While I don't see any obvious faults in the logic here, it feels like
there's a bit more code than necessary.  But I know this is being
modeled after existing code so probably best for this patch to just
follow suit.  However, would be nice to have a follow up patch that
factors out common code chunks into a helper function or two to condense
the code a bit.
