Just FYI this is a good internal WebKit ASSERT. RefCounted does NOT
work well with different threads and this is designed to pick up
internal abuse. However I don't think there is a way for you to change
the verifier without changing WebKit even if you provide your own
synchronization and don't abuse the API.
The best course would be to file a bug on webkit.org about that. The
JSC gurus could then decide the best way to handle that.
