I know proposals to drop the review vote limit have been denied, so I'll propose a compromise.
Today's the biggest edit queue I've seen yet, but I have thought this before. I went to the edit queue, it was at 131. I ran out of votes, reloaded the page, and it was down to a measly 115. I think when the queue is so big, we should have extra votes so we can work through the backlog. Now, how this could be implemented is tricky, largely because on SO it takes two votes to accept/reject. What I am thinking is that after we run out (perhaps when the queue is over a certain threshold) we can have pending votes on half(?) the queue. For instance, let's say you run out of edit votes and there are 100 votes in the queue. We could then have pending votes on up to 50 of those suggested edits. You come back later, the queue is 80, you can vote another 40 times. You come back, it's down to 25 edits, you don't get any more.
To avoid a discontinuity at 49/50 votes (or wherever the threshold is set), we could also get N - 50 more votes: queue of 55 -> 5 extra; 75 -> 25 extra.
I think this is a reasonable compromise between a few people controlling all the edits and getting through the queue.
