+ * the sense that string equality is the same as pointer equality).
+ * This can be guaranteed for two reasons:

+ * return search results from a lower-level directory if a desktop

+ *
+ * - within a given directory, the string is unique because it's the
+ * key in the hashtable of all app_ids for that directory.
+ *
+ * We perform a merging of the results in merge_token_results(). This
+ * works by ordering the two lists and moving through each of them (at
+ * the same time) looking for common elements, rejecting uncommon ones.
+ * "Order" here need not mean any particular thing, as long as it is
+ * some order. Because of the uniqueness of our strings, we can use
+ * pointer order. That's what's going on in compare_results() below.

- * If application launching occurs via some other mechanism (eg: D-Bus

+ *
+ * If the application is launched via traditional UNIX fork()/exec()

+ * If application launching occurs via some other mechanism (eg: D-Bus
