# This is a complete rewrite of TestResources/Tracker/Pool
# we don't use trackers anymore and just probe/sense the running
# boxes to figure out where we are
# . and their admissible load (max # of myplcs)
# . the pool of DNS-names and IP-addresses available for nodes
#
+# #################### implem. note
+#
+# this model relies on 'sensing' the substrate,
+# i.e. probing all the boxes for their running instances of vservers and qemu
+# this is how we get rid of tracker inconsistencies
+# however there is a 'black hole' between the time where a given address is
+# allocated and when it actually gets used/pingable
+# this is why we still need a shared knowledge among running tests
+# in a file named /root/starting
+# this is connected to the Pool class
