the two bugs are (were) in old-school tracing which is what i never use

the par builder code is pretty compatible (although it gives on purpose 
different but consistent results with hz .. the new hz code was 
prototyped this way) .. i still need to find a real application for it

fyi: the code is already kind of old and evolves stepwise into a 
pluggable framework (i reported on this several times in articles and 
status documents)
