    Description

      Internal transactions added logic to the SessionCatalog and it's a relatively contended mutex, so we should audit the code to see if there are any straightforward optimizations we can make to reduce the work done while the mutex is held. Similarly, we should check if are places we take the mutex unnecessarily.
