I think we've overloaded that field too much already. The field is
called 'tid' and tid means thread id and thread id means the LWP id.
If we want to export a pointer to the kernel thread structure then we
need to do it with a new field.
It wasn't ment to be a pointer, just an identifier. And the td pointer is a perfect identifier. Of course, it doesn't format as nicely as a small number, but so what. pid == -1 means kernel, tid *always* means thread identifier.
