+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ The reason this matters:
+
+ The principle downstream from Mir (Unity8) loads Mir as one of a number
+ of plugins, several of which use protobuf. That means that we're prone
+ to being loaded, unloaded and reloaded and don't have control of this.
+
+ We've encountered problems in this scenario before that have been traced
+ to protobuf so we have a specific test. But other Unity8 plugins may
+ encounter the same issue.
+
+ As seen in comment #25 the problem here is entirely down to a change in
+ the behavior of libmirprotobuf-lite - it no longer unloads on dlclose().
+
+ This is only a problem because there is code (see patch in comment #20)
+ that assumes that the library will not be used after a call to
+ google::protobuf::ShutdownProtobufLibrary() unless it is reloaded.
