[JENKINS-70244] Gradle jobdsl tests timing out since 2.357 - multibranchPipelineJob - loop over many repos

Apologies if this is not the correct place to log this issue

We have gradle tests that we run on our jobdsl jobs

Since upgrading the jenkinsVersion we are getting timeouts for our tests, for a larger file which defines a number of repos that we loop over to create multi-branch pipeline jobs

I have pinned this down to v2.357 introducing the issue, with v2.356 working as expected

I have pushed the code to test to repo - https://github.com/psimms-r7/jenkins-2.357-breaking-job-dsl-gradle-tests

Running "./gradlew test" here will fail, however amending the jenkinsVersion to 2.356 will pass

See attached debug log
