[CI] InternalEngineTests testMergeThreadLogging failing

[DaveCTurner]

Also seen in a local run of ./gradlew :server:test but doesn't easily reproduce, even when running many iterations in a loop.

Build scan: https://gradle-enterprise.elastic.co/s/kbbpmnbim32ck/tests/:server:test/org.elasticsearch.index.engine.InternalEngineTests/testMergeThreadLogging

Reproduction line: ./gradlew ':server:test' --tests "org.elasticsearch.index.engine.InternalEngineTests.testMergeThreadLogging" -Dtests.seed=A7B12EB0B151C9B5 -Dtests.locale=es-PA -Dtests.timezone=Europe/Tiraspol -Druntime.java=17

Applicable branches: main

Reproduces locally?: No

Edit to add: eventually this failed for me after a couple of thousand iterations on a machine that was concurrently running stress-ng --timeout 0 --cpu 16
