Update: this is bug report 15602. The response from the Livecode folks is that 7.0.x is using 16-bit numbers for the recursionlimit property, so Jacque hit the nail on the head. However, in 6.x.x they were using 32-bit numbers, so my setting a very high recursion limit actually did have an effect. They confirm that this is a bug. No promise on the timing of a fix, though.

> I'm not sure about the 30,000 issue, but 65535 is the upper limit for a 16-bit number. It may be that earlier versions of LC just didn't throw any errors if you exceeded that.
