It seems that accessing node_count using the same technique 
as with ordered_unique does not work - I'm off by 4 bytes
(see the (((char*)&$c)+4) expression).
Umm... I've been thinking a little more about this and it turns
out that we can do the downcast legally without resorting
to the multi_index_helper_3 hack. The following should work for
any kind of header_holder:

  size : (($T2*)&$c)->node_count

because T2 actually derives from header_holder<*,T2>. This
would allow us to dispense with multi_index_helper_3 entirely.
Can you check this out?
