      Description

      When one entity have multiple nested levels and associated to 700+ other entities, the ORM exhausts a large amount of memory and execution time which exceeds either the memory limit or the maximum execution time.

      Prerequisite:

      1. generate an entity, named "Mr. G", with 4 nested levels of association.
      2. ensure that the generated entity associating to 700+ entities.
      3. create a post-load event listener which may or may not be restricted to uninitialized proxies.

      How to Reproduce:

      1. have a code to load the "Mr. G" entity.
      X. (Done)

      Notes:
      The initial investigation indicates that UnitOfWork should not trigger the post-load event for uninitialized proxies.

      One thing worth-mentioning is that if the event listener ignores all proxies, we will not have this problem. However, some properties (e.g., ones of type TEXT/BLOB) are not loaded into normal entities but they are loaded into the proxies.
