    Description

      While testing MongoDB on PowerPC, we found a situation where reads were not repeatable in a transaction running at snapshot isolation. In particular, with multiple threads inserting and deleting records, we saw:

      begin transaction with isolation=snapshot
      		 
      search for ID=X, found
      		 
      ...
      		 
      search for ID=X, not found
