Can you ensure that GC tests are written in a form like that (https://trac.webkit.org/changeset/261391/webkit)? Testing *one* object's liveness is bad pattern because of conservative GC. Let's test many objects and at least one is dead.

This is not a test to make sure that a particular wrapper is GC'd (e.g. a leak test). Therefore, I don't see the issue with using a single wrapper. In other words, if we had a bug, the test would at least flakily fail. If we don't have a bug, the test will consistently pass.
