Do you know of a way to limit your undo stack not in terms of undos (snapshots) but in terms of memory usage? i.e. limit the undo stack to N megabytes of memory?

Furthermore, do you know of any ways to perform automated testing for memory leaks?

In production, no. In a development environment yes. AFAIK, there is no exposed API in the browser to describe the size of the heap. However, you can expose hooks to get this information in a v8 or node instance; snap heap size, run tests, run GC, snap heap. Compare before and after in your test runner.
