Or, maybe it is also possible with one mapping which is writable first when you fill it with code, then gets flipped over to executable when you are done with the initialization and want use it. Is that correct? I suspect supporting that in tcg isn't exactly trivial. Does OpenBSD work the same way btw? cheers, Gerd
