Yes. To use your terms, I prefer incrementing over thresholding.

If we go with incrementing, then getrecursionlimit should likely decrement the returned value by the same amount, so that setrecursionlimit(getrecursionlimit()) doesn't change the recursion limit.

This is another issue that incrementing avoids.

Since it looks like we're in general agreement, Terry, I'll work up a PR.
