Serial formatting does not help, because for forward references you
would have to look into the future.  If the references don't resolve
as predicted, you get a warning and you just rerun LaTeX.  Nomally
(and I have never seen any deviation from this) it is fixed after the
second run.  If it is not resolved after several runs, the solution is
to change the source such that this does not happen.

That's a classic problem.  The usual solution is to start with all
offsets short, have a pass and remember those that don't fit; repeat
the same, with long offsets for those that did not fit.  Repeat until
everything fits in the space allocated to them.  One can construct
funny problems where this is suboptimal, but in the usual case, this
is also optimal.
