+ *
+ * From the GDB documentation:
+ * Note that for all async output, while the token is allowed by the
+ * grammar and may be output by future versions of gdb for select async
+ * output messages, it is generally omitted. Frontends should treat all
+ * async output as reporting general changes in the state of the target
+ * and there should be no need to associate async output to any prior
+ * command.
+ *
+ * After further investigation, I determined that newer GDB's will no
+ * longer ever output this information. Older GDB's will. The commit
+ * that made this change in GDB is 721c02de on April 24th, 2008.
+ * The next GDB that was released was on October 6th, 2009, version 7.0.
+ *
+ * Before the above mentioned commit async *stopped commands would
+ * sometimes output the token associated with the last token provided in
+ * a GDB/MI input command. After that change, the token is never
+ * associated with an async output command, even though the
+ * documentation says it might be.
+ *
+ * Finally, even before that change when the token was output in the
+ * async *stopped command, the developers of GDB felt that it was not
+ * useful and should be avoided by front ends.
+ *
+ * With this information, I've determined that front ends should never
+ * use this value to determine logic. However, the value is parsed in
+ * order to accurately handle and represent the cases where this value
+ * occurs.

+ * This represents the token value the front end provided to the
