It's difficult for V8 to handle Error.stackTraceLimit in the snapshot, so delete it from the Error constructor if it's present before snapshot serialization, and re-install it after deserialization. In addition try not to touch it from our internals during snapshot building in the first place by updating isErrorStackTraceLimitWritable().
