Yes, I'm certain. See ch. 14 of the TeXbook (you can download that book, 
btw). In fact our use of the value 10000 was taken from Knuth's example, 
who takes 10000 to mean "infinity".

I think this is perfectly reasonable, at least if you're trying to fill 
out pages. 5 systems=1 page, 10 systems=2 pages.
