+Subject: [PATCH] tests: Lower number of iterations in network-monitor-race
+
+While 333 runs is very likely to reproduce the bug, Milan has previously
+reproduced it with as few as 9 runs. Since this test will be run by the
+CI machinery quite often, a lower number of runs each CI run will still
+probably catch any regressions over time.
+
+This reduces the total test runtime from 33s to 2s.

+Subject: [PATCH] tests: Allocate gvariant data from the heap to guarantee
+ alignment
+
+On glib-2-58 branch we don't have !455, thus we need aligned data
+for the gvariant tests to not fail on i686.
+
+Fixes #1626
