Which serverside lag macro does currently work in 6.2?

[crunk001]

/run for v=1,5 do for i=1,10000 do C_Heirloom.CreateHeirloom(122263) end end

was this actually serverside? I can set the value any higher. The macro does nothing. For example v=6

/run local t = time() + 4 while time() < t do end

this is not server-side for me, others can freely attack / interact with me as if I wasnt using any macro at all

What would be required is simply a macro that lags the character out for x seconds and keeps him logged in. Is that possible?
