This issue manifested in a crash in rare circumstances when the Editor lost and gained focus while a modal dialog was active. After investigation, it was discovered that native event processing can lead to IdleProcessing being called again from the main thread while idle processing is still happening. As this is unintentional and generally undesirable, we now guard against this within the IdleProcessing method.
