+ * IKM background connection manager for IM-using queue handlers,

+ *
+ * In a multi-site queuedaemon.php run, one connection will be instantiated
+ * for each site being handled by the current process that has IM enabled.
+ *
+ * Implementations that extend this class will likely want to:
+ * 1) override start() with their connection process.
+ * 2) override handleInput() with what to do when data is waiting on
+ *    one of the sockets
+ * 3) override idle($timeout) to do keepalives (if necessary)
+ * 4) implement send_raw_message() to send raw data that ImPlugin::enqueueOutgoingRaw
+ *      enqueued
