How to properly use both Destroy and DestroyImmediate for mixed editor/game code

Hi,

I'm new here so I hope I'll make myself clear... I have an algorithm (re)generating a mesh which is called both in game and in editor.

To save memory, I split the mesh into chunks, which I destroy when I don't need them anymore. To do this, I have something like this :

 if (Application.isPlaying)
 {
     Destroy(holderTransform.gameObject);
 }
 else
 {
     DestroyImmediate(holderTransform.gameObject);
 }

The thing is DestroyImmediate "is not permitted during physics trigger/contact, animation event callbacks, rendering callbacks or OnValidate", which happens in editor mode.

But what should I do then, as the Destroy method isn't available in editor ?

Thanks for your ideas !
