+ * @class ACE_LOCK_SOCK_Acceptor

+ * @brief Specialize ACE_SOCK_Acceptor to lock around <accept>;
+ *
+ * This class is necessary since some OS platforms (e.g.,
+ * Solaris 2.5) do not allow multiple threads/processes to
+ * simultaneously call <accept> on the same listen-mode
+ * port/socket.  Thus, we need to protect against multiple
+ * concurrent accesses by using the appropriate type of lock.
