Speaking for myself and not the SRU team as a whole, I think this issue
has reached the level of complexity to analyse effectively that it's not
worth doing an SRU given: 1) the risk to existing, unaffected users,
including the risk that analysis has missed something; and 2) the
theoretical bug issue that remains, that nobody else has hit since
Noble's release, once the sysctl workaround has been tweaked and that
requires a very unusual set of circumstances to replicate.

To be clear, I think Wesley's analysis is excellent given the complexity
involved. But it is a complex area, and with that complexity comes risk,
which is why we try not to make deep changes in stable releases.

I'll leave it for other SRU team members to reach their own conclusions,
and then I guess we'll need to make a collective decision.
