It worked for me with 5014 but not 5013.  So it seems even 7500 would

I don't know of a good and portable way to do this.  There are (have
been) a number of TeX implementations that have handled configuration
differently.  In the old days you would have had to recompile TeX in
order to increase its capacity.

With a modern TeX that uses texmf.cnf and has kpsewhich, I suppose you
could do something like

  sed 's/save_size *= *[0-9]*/save_size = 10000/' $(kpsewhich texmf.cnf) > 
texmf.cnf-t && mv texmf.cnf-t texmf.cnf
  TEXMFCNF=. pdflatex ...

(you might also want to add save_size if it is not already present).
But doing something like this seems a bit of a kluge, and again, not
portable.

I don't see a way to tell TeX to read a series of configuration files
so that you can let it read the system-wide texmf.cnf file then read
another one that contains just "save_size = 10000".

Should we disable the expansion of @seealso by default, and only do it
when specifically requested?  Or should we just let builds fail, and
tell people to increase save_size in their TeX isntallation?  If we do
that, we should also ask the people who package TeX to consider an
increase in this parameter for us.
