Andrew and I have discovered that on Linux max peak rss valueis taken to be max(build_runner, test_suite) and since the thunkstest emit a huge binary, we will easily exceed the declared maximumfor any of the test suites. This can be worked around for now by notchecking for $thunk symbols in this test since it doesn't reallyyield any additional information; however ideally we would implementper-thread local temp arena that can be freed.
