+commit 7c38c8cf28a4d0d667e23ddfaaf38a955d65bf3e
+Author: Aleix Pol <aleixpol@kde.org>
+Date:   Wed Sep 22 16:19:39 2021 +0200
+
+    Ensure categories.xml is only fetched once in parallel
+    
+    Otherwise we overload the server that is returning them fairly slowly
+    anyway (2 to 3 seconds?). It seems like it serves these sequentially as
+    well, which makes Discover startup stuttery.
