There is an occasional failure due to "no sessions" in the "audit integration tests: flexible sync: auditing with a flexible sync user reports a sync error"

This was observed during the build for the prepare-13.4.0 pull request.

Test Run: https://spruce.mongodb.com/task/_macos_release_object_store_tests_patch_476a2ad850aea98600c2430135adea0d27ee20e4_63dd96672a60ed69426589fd_23_02_03_23_19_05/logs?execution=0&sortBy=STATUS&sortDir=ASC

It's not specific to "flexibel sync" or any particular sub-case test. From log you can see that it actually crashes on cleanup of TestAppSession after the main testcase piece. For me it also fails occasionally localy in different 'audit' tests, from TestSyncManager also:

Quite easy to reproduce with ./realm-object-store-tests -b "audit management" -c "ending invalid scopes".
Also still happens with latest 13.4.2 after #6293

➤ michael-wb commented:

This error may be caused by a race condition due to the fact that SyncClient::stop() does not wait for the sessions to be fully closed before returning.
A possible fix may be to update SyncClient::stop() to take a bool parameter and either call Client::shutdown() or Client::shutdown_and_wait() based on it's value. Then update the reset_for_testing() to call the stop function so it waits for shutdown.

➤ Jonathan Reams commented:

I think this is a race between SyncManager::reset_for_testing() which tries to force-tear-down the sync manager and all its sessions, and the teardown of the audit worker and any sync sessions being used by auditing. Looking at the stack trace below, we see that we're crashing in reset_for_testing() because it was able to find a valid external reference, and that the audit worker thread is blocked trying to acquire the mutex that reset_for_testing() holds.
