Sorry, I don't see anything - it seems to boil down to the same code in
the DA and non-DA case as far as I can tell, but after a while all the
twisty passages seem to look alike.

If Ingo confirms that the recv end was running the locking patch code,
it would be interesting to just confirm the sysreq+t looks the same as
before - it is possible the patch turned the race into a non-obvious

I'm sure your smaller revert will make the problem go away just as the
larger one did, fwiw. 

The other odd thing is that Ingo did a lot of experimentation and was
only making this happen on localhost before (though I agree there is
nothing inherent about that lock and localhost) - isn't it odd that the
first trigger of it now is between two hosts? What do you make of that?
