When running the test TestLargeJavaEvent64k.java we do not reach safepoint within 10 seconds.

It seem walking the JfrDoublyLinkedList is extremely slow.
I have looked at this list before and from what I remember this is not an issue in product.
Since the list is clobbered with asserts I suspect it is them causing the issue.

I propose we create gtest and remove the internal asserts.
