I can also reproduce it by building 2.54.1-1 or 2.54.2-2 and re-running
that test in a loop, but not easily (running 100 times in a loop often
succeeds). Having looked at the history of the code involved, I think
this is a long-standing race condition; so this isn't a regression,
and shouldn't block testing migration.
