+#
+# We use it to check pipelining - a client sents 8 questions over a
+# pipelined connection - that require asking a normal (examplea) and a
+# slow-responding (exampleb) servers:
+# a.examplea
+# a.exampleb
+# b.examplea
+# b.exampleb
+# c.examplea
+# c.exampleb
+# d.examplea
+# d.exampleb

+# If pipelining works properly the answers will be returned out of order
