+ *
+ * Group lock is a synchronization object to manage concurrency among members
+ * within the same logical group. Example of such groups are:
+ *
+ *   - dialog, which has members such as the dialog itself, an invite session,
+ *     and several transactions
+ *   - ICE, which has members such as ICE stream transport, ICE session, STUN
+ *     socket, TURN socket, and down to ioqueue key
+ *
+ * Group lock has three functions:
+ *
+ *   - mutual exclusion: to protect resources from being accessed by more than
+ *     one threads at the same time
+ *   - session management: to make sure that the resource is not destroyed
+ *     while others are still using or about to use it.
+ *   - lock coordinator: to provide uniform lock ordering among more than one
+ *     lock objects, which is necessary to avoid deadlock.
+ *
+ * The requirements of the group lock are:
+ *
+ *    - must satisfy all the functions above
+ *    - must allow members to join or leave the group (for example,
+ *      transaction may be added or removed from a dialog)
+ *    - must be able to synchronize with external lock (for example, a dialog
+ *      lock must be able to sync itself with PJSUA lock)
+ *
+ * Please see https://trac.pjsip.org/repos/wiki/Group_Lock for more info.
