+ * message for which the client is waiting a reply. This is needed
+ * to determine if an error matches a replyWait.
+ *
+ * - replyWait->major_opcode_of_request is the major opcode of the
+ * message for which we are waiting a reply.
+ *
+ * - replyWait->minor_opcode_of_request is the minor opcode of the
+ * message for which we are waiting a reply.
+ *
+ * - replyWait->reply is a pointer to the reply message which will be
+ * filled in when the reply is ready (the protocol library should
+ * cast this IcePointer to the appropriate reply type). In most cases,
+ * the reply will have some fixed-size part, and the sender function
+ * will have provided a pointer to a structure (e.g.) to hold this
+ * fixed-size data. If there is variable-length data, it would be
+ * expected that the reply function will have to allocate additional
+ * memory and store pointer(s) to that memory in the fixed-size
+ * structure. If the entire data is variable length (e.g., a single
+ * variable-length string), then the sender function would probably
+ * just pass a pointer to fixed-size space to hold a pointer, and the
+ * reply function would allocate the storage and store the pointer.
+ * It is the responsibility of the client receiving the reply to
+ * free up any memory allocated on it's behalf.
+ *
+ * We might be waiting for several different replies (a function can wait
+ * for a reply, and while calling IceProcessMessages, a callback can be
+ * invoked which will wait for another reply). We take advantage of the
+ * fact that for a given protocol, we are guaranteed that messages are
+ * processed in the order we sent them. So, everytime we have a new
+ * replyWait, we add it to the END of the 'saved_reply_waits' list. When
+ * we read a message and want to see if it matches a replyWait, we use the
+ * FIRST replyWait in the list with the major opcode of the message. If the
+ * reply is ready, we remove that replyWait from the list.
+ *
+ * If the reply/error is ready for the replyWait passed in to
+ * IceProcessMessages, *replyReadyRet is set to True.
+ *
+ * The return value of IceProcessMessages is one of the following:
+ *
+ * IceProcessMessagesSuccess - the message was processed successfully.
+ * IceProcessMessagesIOError - an IO error occured. The caller should
+ * invoked IceCloseConnection.
+ * IceProcessMessagesConnectionClosed - the connection was closed as a
