+Subject: [PATCH 1/2] Revert "Handling collision between standard i/o file
+ descriptors and newly created ones"
+
+g_unix_open_pipe tries to avoid the standard io fd range
+when getting pipe fds. This turns out to be a bad idea because
+certain buggy programs rely on it using that range.
+
+This reverts commit d9ba6150909818beb05573f54f26232063492c5b

+Subject: [PATCH 2/2] glib-unix: Add test to make sure g_unix_open_pipe will
+ intrude standard range
+
+Now that we know it's a bad idea to avoid the standard io fd range
+when getting pipe fds for g_unix_open_pipe, we should test to make sure
+we don't inadvertently try to do it again.
+
+This commit adds that test.
