Given:
Execute the CompetingMessageCorrelationTest#testConcurrentMixedCorrelation() test case on CRDB.

When:
The test tries to continue the non-exclusive thread.

Then:
The test execution blocks.

Expected:
The test execution continues and succeeds.

Note:

• The test case uses a concurrent execution of an exclusive (SELECT FOR UPDATE) and non-exclusive message correlation. We need to understand how SELECT FOR UPDATE works in CRDB to understand why this setup causes a deadlock.
