A question:
Does anyone know any other country than a predominantly Muslim coutry with the (theoretical) death penalty (or any other penalty) for apostasy? I did a short search and found none, but it wasn't an exhaustive search.

Without a search, just from memory:
St. Stephen (Jerusalem, stoned), Jan Hus (Germany, at the stake), Savonarola and Giordano Bruno (Italy, at the stake), Michael Servet in Geneva (Switzerland, at the stake), all for heresy.

Times begone, thanks to God
