Symbols are never freed, so, it's better to use several separate [text2d] 
to reduce the total number of symbols created.

Otherwise, as tens of thousands of symbols are created, not only it takes 
RAM, but it also slows down the symbol table (this means it slows down any 
uses of gensym).

[text2d] could be modified to also accept lists of ascii codes. In that 
case, [#sprintf] can do the job of multiple [makefilename]s (and more) 
without creating any symbol. You just need [#to_list] to make it a plain 
pd list.
