Jira issue: CRDB-68213

Start with the linked TeamCity build log and artifacts for sql/catalog/lease.TestLeaseManagerLockedTimestampBasic, then inspect the goroutine locations cited in the failure, including pkg/util/admission/work_queue.go and the Pebble files. Re-run the named test on commit 6f06279e7915577f2c8a2d20752ef6c99e78707b and use the failure output to identify the cause; done means the failure is fixed and the test passes.
