+ * while suspended in the inactive state, you will return to the
+ * empty state if you do not insert a new card and to the inactive state
+ * if you do insert a new card.
+ *
+ * Some might argue that inactive should be sticky forever and
+ * eject/insert shouldn't take it out of that state.  They might be
+ * right.  On the other hand, some would argue that eject resets all
+ * state.  They might be right.  They both can't be right.  The above
+ * represents a reasonable compromise between the two.
+ *
+ * Some bridges allow one to query to see if the card was changed while
+ * we were suspended.  Others do not.  We make no use of this functionality
