Ok, I see - I was looking to see if was doing anything clever, but hadn't found
the point where the allocated memory was inserted into a list - but I've
seemingly missed it. This must be the location of insertion in the
__request_resource function?
for (;;) {
tmp = *p;
if (!tmp || tmp->start > end) {
new->sibling = tmp;
*->>>>>* *p = new;
new->parent = root;
return NULL;
}
p = &tmp->sibling;
if (tmp->end < start)
continue;
return tmp;
}

Yes, thanks for your feedback.
