    Description

       

      We recently made a change in WT-6164 to fix a problem where we added a new flag to a set of flags - and that caused the flag values to overflow. The symptom was that there was significant memory growth - since the flag now missing was related to freeing update structures.

      The fix in WT-6164 seemed to work in some scenarios and not others - we need to investigate further to understand where the remaining leak is.
