There are a few test cases in TestMultithreaded.py. Most of them set a breakpoint by name on "next". There's no problem with doing that, but one of the tests cases in particular relies on being able to grab a specific breakpoint location corresponding to the test inferior. If you have libc++ symbols, this test will also have breakpoint locations for symbols named `next` in libc++. I could have changed the test to find the correct `next` breakpoint location, but it seems easier to give it a more uncommon name instead.
