Lag spike with UnitMakeAbilityPermanent

Yeah, title says it all.
Can this be avoided?

Tried making this at map start, but it had no visible effect. Perhaps me not coding it correctly, dunno.

Preload spell? Show code.
I use UnitMakeAbilityPermanent in loops and execute the loop periodically (T32) without lag spiking.

I found out where the problem REALLY lies -.-
It's not the ability that's made permanent, but the ability behind it... Well hard to explain in a few lines.

Thank you anyway (+rep)
