Subject: [PATCH] [kernel|global|test] Tweaking

Add loop-counter (in the process dictionary) to the
'loop until true' function (for debugging).
Also, when receiving a timetrap timeout (from ct) during
'wait for ready net', also include the dictionary (so that
the loop-counter is shown in the printout). And finally
kill that process (which is waiting).
