This is a backport of core#20748

Test Plan:
With TSAN:
for i in $(seq 100); do TSAN_OPTIONS=second_deadlock_stack=1: TSAN_OPTIONS=suppressions=/home/pierre/dev/bitcoin-abc/test/sanitizer_suppressions/tsan test/functional/test_runner.py interface_zmq; done

This failure is intermittent, but relatively easy to reproduce: I was able to get it with 10 repetitions of the test, prior to adding the suppression.
