+In December 2014 / January 2015 did a lot of changes to ICMP pinger (IPv4) which were
+  not replicated in TCP pinger nor in ICMPv6 pinger. Should check if same changes 
+  need to be applied there, too. In particular, the scheduling of reply receive 
+  handlers in ICMP caused trouble, often encountered 'ghost' packages which were all
+  0s because a handler for an old echo request was triggered without new data.
+
+Also, removed threads for each pingchecker, leaving only one thread with one 
+  io_service for all pingers. Tested that a lot with ICMP v4 pinger, but no other.
+
+If the system time is changed backwards, the pingchecker freezes, including its signal
+  handler (boost asio's deadline_timer seems to work with time points on a non-monotonic
+  clock). Change that! (apparently, boost asio 1.49 introduces a steady_timer, try that)
