 Cool, thanks for looking into this!  I was planning to investigate at
 some point soon, starting by adding dtrace probes (and maybe wiring up
 the sysctl knobs) so we can reproduce the analysis of the issue in the
 field.  Your analysis sounds plausible, but I'd like to make sure we
 have the visibility to verify the behaviour -- and the change in
 behaviour -- first!
