Like Noah said, in order for it to scale to an unlimited number of
rooms, you need to divide your algorithm to run over multiple
execution rounds. (Or were execution rounds called tasks now? I keep
forgetting.)

This is done using the call_out() kfun, as you may already know...

One example of how that could be done is to remove the loop and what
comes after it from your main function, and instead call a function
there, that does something like this:

void print_nodes_step (string *files, varargs int i)
{
    do
    {
        if (i >= sizeof(files))
        {
            break;
        }

        print_node(files[i++],str);
    }
    while (status()[ST_TICKS] >
SOME_NUMBER_SUFFICIENTLY_BETWEEN_0_AND_MAX_TICKS)

    if (i >= sizeof(files))
    {
        write_file(filename,"}\n");
        write_file(filename,"# End: str\n");
    }
    else
    {
        call_out("print_nodes_step", 0, files, i);
    }
}
