Reading through that thread, I see what K meant now. Problem solved, mostly.
As it happens, I think he's wrong, but I'll read through the rest of the thread before I post about it, since the post I'd be responding to is over two years old.
So, Tshern's "Peculiar necromancy" thread got me thinking about rebuking.
One thing I noticed bothered me somewhat while I was looking around for ways to either boost rebuking or create a Planetar Zombie with high wisdom. In K's Revised Necromancer Handbook, he states (on Necromantic Presence + Rebuking) "Hilariously, when you take over an undead monster when you have this ability, it gains +4 Turn Resistance: almost assuredly making it ineligible for you to control it".
Does it really work that way?
Here are the interpretations of rebuking I can come up with, though there are likely others. The examples are mostly because I'm somewhat ill and rather tired; I'm using them to organize my thoughts.
EHDfT: Effective hit dice for turning. I got sick of typing it out at some point.
Evilpants: Dread Necromancer 6 with no bonuses or penalties to rebuking. He has a friend with a Lyre of the Restful Soul.
Radius: 7HD Skeleton with no turn resistance.
Ulna: identical to Radius, but is a separate skeleton.
1: Effective HD for rebuking is checked constantly.
Evilpants rebukes Radius while his bard works the Lyre. His effective rebuking level is greater than or equal to twice Radius' effective HD for turning (3), so the skeleton is rebuked. When the Lyre wears off, Radius has 7 effective HD for turning once more, making Evilpants unable to control it. Results: Evilpants regrets not using Command Undead instead.
2: Effective HD for rebuking is only checked while resolving the rebuke attempt. Therefore, how many you can fit in your control pool is dependent upon how much you can lower the target's EHDfT before rebuking them.
Evilpants rebukes Radius while his bard works the Lyre. His effective rebuking level is greater than or equal to twice Radius' effective HD for turning (3), so the skeleton is rebuked. When the Lyre wears off, Radius has 7 effective HD for turning once more, but it does not invalidate Evilpants' control because the controlled creature only needs to be a legal target when the rebuke attempt is resolved. Evilpants later encounters Ulna, and attempts to rebuke it too (w/Lyre of course). He succeeds, and now controls both Radius and Ulna. His rebuke control pool is at 6/6 HD (since each of the skeletons were 3EHDfT when rebuked), so if he wishes to gain control of more things, he'll have to dismiss his control of Radius or Ulna.
3: Effective HD for rebuking is only checked while resolving the rebuke attempt, but another rebuke attempt will check the current EHDfT of the undead in your control pool.
Evilpants rebukes Radius while his bard works the Lyre. His effective rebuking level is greater than or equal to twice Radius' effective HD for turning (3), so the skeleton is rebuked. When the Lyre wears off, Radius has 7 effective HD for turning once more, but it does not invalidate Evilpants' control because the controlled creature only needs to be a legal target when the rebuke attempt is resolved. Evilpants later encounters Ulna, and attempts to rebuke it too (w/Lyre of course). He doesn't have space in his rebuke control pool, which is at 7/6 HD (since his commanded creatures total 7EHDfT right now).
2 or 3 would be much more congruent with existing mechanics in D&D, specifically that of spellcasting.
Is there any rules text that supports or undermines any of these? If so, where can I find it?
