There is no way to remove entity cache items

Added the method body.

Thanks for reporting!

Will most likely need a test case showing this bug

Nice issue summary!

Thanks for this, this is very helpful!

I have run into this issue lots of times and have come into the habit of copy-pasting the following stanza to various services in various projects for exactly this purpose:

  protected static function reclaimMemory(): void {
    $memory_cache = \Drupal::service('entity.memory_cache');
    assert($memory_cache instanceof MemoryCacheInterface);
    $memory_cache->deleteAll();
    gc_collect_cycles();
  }

I never figured out how to properly solve this issue, though, great work on that! Not sure how to write a test for this, as the concrete memory usage at any given point is always a bit unpredictable, but maybe someone will have an idea. Definitely bookmarking this and will give this a spin when I get a chance.
