Technically speaking, --slow_path is not synonym with --no_inline_alloc.
We discussed last week the benefits of keeping the --slow_path flag. They are
not huge. We may remove the flag at some time. Any opinion?

I'm using --no-inline-alloc here. We should have at least one flag for testing
purposes. A generic slow-path - I don't know where it should be used, so I would
be fine with removing it.

+  }

+main() {
+  const int N = 100000;
+  testCollection(new LinkedHashSet(), N);
