Yes, you're right; it is configurable now.
In earlier versions of TeX this was a pre-compiled limit;
but that's probably dark-ages ago now.

Later I got a different message which indicated that the limit of 
125000 bytes of pool
was exceeded.
After that, I tried   sudo vi `kpsewhich texmf.cnf`
and successfully expanded the pool by a factor of 10.
That did the trick --- so my knowledge of such things
also expanded a little.


Of course this begs the question of writing lines such as
   pool_size.xetex = .....
   pool_size.xelatex = .....
into texmf.cnf upon installation.

BTW, can we have an iChat sometime soon, concerning issues
arising from the San Francisco TeX meeting ?
