Maybe this would be a good place to use test_perf_cleanup, which I
introduced a while ago and you can find in the
tg/perf-lib-test-perf-cleanup branch?  It probably won't influence the
performance a lot, but still better separate the code that actually
needs to be tested from the cleanup/preparation code.  Ditto in the
other test.
