+// created. The return value will be true if we are to retry launching
+// chrome (and show the 'chrome has crashed' dialog) or to silently exit.
+//
+// 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.
+// The wording and localization is up to the operating system.
+//
+// Do not call this function for memory related errors like heap corruption
+// or stack exahustion. This function assumes that memory allocations are
+// possible.
