+// This function only handles a few known exceptions, currently:
+// - Failure to load a delayload dll.
+// - Failure to bind to a delayloaded import.
+// - Fatal Graphics card failure  (aura build only).
+//
+// If any of these conditions are encountered, a message box shown by
+// the operating system CSRSS process via NtRaiseHardError is invoked.

+// Do not call this function for memory related errors like heap corruption
+// or stack exahustion. This function assumes that memory allocations are
