Not approved.
I get the same error as reported at LPP-5173. But after I've removed the
call to LzSprite#destroy(..) in LzReplicationManager#destroyClone(..),
the error was gone. So, why do we call directly LzSprite#destroy(..) at
that place?
Notes:
- with this change, you can revert my changes for LPP-4879 regarding
updatePlayDel/doQueuedDel in LzSprite#predestroy resp. #destroy (SWF)
- the current implementation will be quite inefficient for DHTML,
because in DHTML we still recurse in LzSprite#destroy...!

Summary: Fix Sprite memory Leaks
Bugs Fixed:
LPP-5217 'windows can leak memory
Technical Reviewer: [EMAIL PROTECTED] (pending)
QA Reviewer: [EMAIL PROTECTED] (pending)
Doc Reviewer: (pending)
Details:
LzSprite.*: In #destroy set __LZdeleted flag to prevent events
from resurrecting you. No need for recursive sprite destruction
now.
LzIdle: Be careful to create coi Array on instance, not prototype.
LzNode: Add comment to explain importance of __LzDeleted flag.
LaszloView: Destroy the sprite _before_ you check for a recursive
call.
newcontent, scrollingtext: Remove unused id (that causes a leak).
Tests:
I modified Phil's test case to only create/destroy 1 window per
click. The test methodology is:
1. Start test
2. Click twice to create any shared substrate
3. Debug.markObjects()
4. Click once
5. Debug.findNewObjects()
6. Debug.whyAlive()
Result: Before change, many leaked window sprites. After change, no
leaked window sprites.
NOTE: There are still some other minor leaks that I have not
attempted to address here, but will report as a separate bug.
