-- when connecting to a running app, we cant easily get the 'current' state if logging
-is using a socket, as past events are not stored
+ gst_deinit() (apps can call it from atexit())
+- how to share the quark table from gst/gstquark?
+ use a separate table in gst/gsttracers or add a getter to gst/gstquark
+- how to chain tracers (use the rank?)
+ e.g. how can the stats tracer get data from rusage/mallinfo tracers
+ or should all tracers just log and we would use a gst-stats tool to collect
+ the data from the log and process it then (that would also solve the deinit()
+ issue)
