+ * possible to distinguish between a return value and an exception.
+ *
+ * This function is useful when you need to pass the result of a call across
+ * a process boundary (across which exceptions don't propagate).  It probably
+ * doesn't need to be factored out into this module, since it is only used by
+ * a single caller, but putting it here works around bug 625560.
