Erro de initex do TeX "Capacidade do TeX excedida, desculpe [tamanho do pool = 8563]" enquanto a constante pool_size está definida como 350000. O que posso fazer?

Question

Atenção: Este TeX é gerado porweb2js Compilador WEB/TeX Pascal para WebAssembly de Jim Fowler.

Esta é uma pergunta complementar paraÉ possível gerar uma constante WEB com um comando TeX (ou WEB)?.

Recebo esse erro lplain.logquando tento despejar o formato lplain.

This is TeX, Version 3.14159265 (INITEX)  4 JUL 1776 12:00

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

Mas a constante pool_size está definida como 350.000 (valor padrão: 32.000).

Aqui está meu tex.sys usado (sem uso de tex.ch):

Tive sucesso com o seguinte TeX_big.sys:

Com um lplaint.texformato, por exemplo, LaTeX 2.09, o sistema TeX_big usa aprox. 350 páginas de memória, ou seja, aprox. 1,4 MB de memória.
