ok, changed it like this:
    NSArray *a = [self componentsSeparatedByString:s];
    NSMutableArray *ma = [NSMutableArray arrayWithCapacity:[a count]];
    int i,j;

    // deep copy of a
    for(i=0,j=[a count];i<j;i++){
        [ma addObject:[NSString stringWithUTF8String:[[a oai:i]UTF8String]]];
    }
    return [NSArray arrayWithArray:ma]; // immutable

but also no difference; I give up. For the moment.
Thanks to all who helped.
