I looked that up in Emacs with C-h v.  It says it's the maximum number
of "redisplay ticks" before some aborting or other occurs.

I don't know what a redisplay tick is, and the dock string doesn't
explain it.  I've never heard of the term before.

This doc string is thus not very helpful, quite the reverse.

Maybe one of the manuals explains it.  It would be nice to have that
doc string amended to be less puzzling.
