When the fix for https://bugs.webkit.org/show_bug.cgi?id=145527 was being prepared, it was believed that the bug involved a race between the main thread GC'ing and a worker thread compiling a DFG replacement for a baseline function. Testing for such a case in a deterministic was considered not worth it. We should make sure that there is test coverage for most / all of the new paths added.
