> If a region entry is destroyed at the same time that a CQ is executed, there exists a race condition where a non-destroyed {{NonTXEntry}} is retrieved during iteration of results in {{CompiledSelect.doNestedIterations()}} but is marked as destroyed/removed before {{NonTXEntry.getValue()}} is called in {{CompiledComparison.evaluate()}}, which results in an {{EntryDestroyedException}} being thrown.

> Surrounding the calls to {{NonTXEntry.getValue()}} in {{CompiledComparison.evaluate()}} with a try/catch block that handles the {{EntryDestroyedException}} will prevent this failure.
