+# end of the pipe, so we get EOF when all other processes have exited.
+# Then the server process unlinks any remaining resource names.
+#
+# This is important because there may be system limits for such resources: for
+# instance, the system only supports a limited number of named semaphores, and
+# shared-memory segments live in the RAM. If a python process leaks such a
+# resource, this resource will not be removed till the next reboot.  Without
+# this resource tracker process, "killall python" would probably leave unlinked
