Research direction

Start by reproducing sql/sqlstats/sslocal.TestTransactionLatencies, focusing on the simple_statements failure reported in sql_stats_test.go:1878. Read the surrounding test and the test_server_shim.go notes, then inspect the linked test logs. Done means identifying and addressing the transaction retry failure so the test passes reliably.
