That's more or less what my code for PushBack does - I changed it to check and ignore requests for 
that buffer address - it gives a message when it does this, and there are such messages appearing in 
the Trace 1 and Trace 2 output.  It's not doing much harm to ignore them, as it seems they are only 
produced by the simulation that is currently being resumed.  That simulation is trying to report a 
trace event to the "outer HHH", but of course that is well and truly gone by this point so there is 
nothing waiting to analyse those entries.  [Bottom line I suppose is the resumptions are heading 
into undefined behaviour, as long as PO's code is misusing global variables.  Once we have pure code 
the whole resumption idea makes good sense...
