+    resolv: Serialize processing in resolv/tst-resolv-txnid-collision
+    
+    When switching name servers, response processing by two server
+    threads clobbers the global test state.  (There is still some
+    risk that this test is negatively impact by packet drops and
+    packet reordering, but this applies to many of the resolver tests
+    and is difficult to avoid.)
+    
+    Fixes commit f1f00c072138af90ae6da180f260111f09afe7a3 ("resolv:
+    Handle transaction ID collisions in parallel queries (bug 26600)").
