+# The test verifies binlogging of XA transaction and state of prepared XA
+# as far as binlog is concerned.
+#
+# The prepared XA transactions can be disconnected from the client,
+# discovered from another connection and commited or rolled back
+# later. They also survive the server restart.  The test runs two
+# loops each consisting of prepared XA:s generation, their
+# manipulation and a server restart followed with survived XA:s
+# completion.
+#
+# Prepared XA can't get available to an external connection
+# until connection that either leaves actively or is killed
+# has completed a necessary part of its cleanup.
+# Selecting from P_S.threads provides a method to learn that.
