Detailed Description

A base class for data structure classes wishing to make iterators ("handles") pointing into themselves fail-fast.

When building without asserts, this class is empty and does nothing.

DebugEpochBase does not by itself track handles pointing into itself. The expectation is that routines touching the handles will poll on isHandleInSync at appropriate points to assert that the handle they're using is still valid.
