Thanks for looking into this, this is the kind of approach I had in mind. From a quick look, checking the circuit breaker is not so cheap, but doing it infrequently, every 8192 terms, should help amortize this cost. I wonder if we should do it even more infrequently, e.g. every 64k terms, since only adding 8k terms should not allocate lots of heap

I upddated it so we do the check every 65536 calls. |

Currently global ordinals are built without any protection against out of memory errors, even though they can use quite a bit of heap. This PR improves the way we build global ordinals by checking the parent circuit breaker every
819265536 calls to TermsEnum#next.
