With the latest patch I posted it passed a private
autobuild.

I'm trying again a few times today but I'm hopeful
I've found it.

The bug with selecting the right slot to replace
could have lead to two contexts with the same tevent_context
being in the array at the same time, which might
explain the problems we've been seeing.

I'll report back after a couple more private autobuilds..
