but how often multiple newreads?

anyway, it's not just bumping a number but also adapting tests as well 
as a bunch of larger static arrays (keep in mind we have callback sin 
input) .. in fact, one can just write thousands of input handlers in lua

and yes, we could have less catcode tables (256 would do probably)

sure, but then we need to get rid of / change some / add to core tex 
thingies too because it's a rather hybrid thing .. never ending
