Comment:
I've found another approach to fix the bug that would need reverting
[2188] (which makes #1907 reappear).
What really caused the problem was that the previous code expected a
certain sequence of execution:
1. Instance 1 defines FCKeditorAPI, and thus FCKeditorAPI.Instances.
2. Instance 2 redefines FCKeditorAPI, and overwrites
FCKeditorAPI.Instances.
3. Instance 1 and 2 add themselves to FCKeditorAPI.Instances.
Because Instance 1 and Instance 2 are executed in different windows,
there's really no guarantee that step 3 will always happen after step 1
and 2 - race condition. This is what happened in this ticket - Instance 1
added itself to FCKeditorAPI.Instances before Instance 2 overwrote it and
cleared it. Thus, after [2188] in sample09.html, either
FCKeditorAPI.GetInstance('FCKeditor_Default') or
FCKeditorAPI.GetInstance('FCKeditor_Basic') would give you undefined.
The real fix to this is to change FCKeditorAPI's code to handle the race
condition, instead of restoring the hack to make the race condition less
likely to happen.
