Instead I went a different route and jumped to HEAD/CURRENT. I'm not seeing the mbufs leaking yet. I'll need another 24 hours to confirm. Hopefully this is a worthwhile clue. I'm a bit surprised nobody else has reported this type of behavior... maybe 10 isn't getting the amount of testing we expect? ...or maybe it's just my lonely, haunted hardware :(

Is it possible for you to bisect head from the stable/10 branchpoint up
to the current date and narrow down the revisions that introduced (and later
fixed?) the leak?
