After diving into the bowels of the drupal code I found the spot which did the creating and it seemed to be doing something quite reasonable with the new node ID.
With just a small amount of convincing I managed to get it to do what I wanted.

Creating a node can now be done like this:
$node = new stdClass();
$node->type = ...;
node_object_prepare($node);
// fill in node details here...$node->request_nid = $my_nid;
node_save($node);
That seems quite trivial now. I don't know why so many people say it can't be done.
