It turns out that there is a second race condition in the new deadlock-hard test: once the deadlock detector fires, it's uncertain whether step s7a8 or step s8a1 will report first, because killing s8's transaction unblocks s7. So far, s7 has only been seen to report first in CLOBBER_CACHE_ALWAYS builds, but it's pretty reproducible there, and in theory it should sometimes occur in normal builds too. If s7 were a bit slower than usual, that could also break the test, since the existing expected-file assumes that we'll see s7a8 report the first time we check it after s8a1 completes. To fix, add a post-lock delay to s7a8.
