      Summary

      DRIVERS-2877 attempted to fix racy unacknowledged write tests by following the write operation with a query:

      Since connection pool size defaults to 1, the next operation will use the same connection, and won't complete until after completion of the unacknowledged write.

      However, it neglected to add useMultipleMongoses: false to the client under test, which means it's possible that the query executes on a different mongos than the preceding unacknowledged write. This resulted in sporadic failures (see: PHPLIB-1461).

      What is the problem or use case, what are we trying to achieve?
