loop detection can have several rules. Looking at the stack of Via 
addresses is not enough usually, it has to check also if the r-uri it is 
different than previous cycle. It can be coded in configuration file 
using htable, but I guess it can get in some level of complexity when 
having to deal with parallel forking. Perhaps a config function doing 
all the logic inside would be nicer, but considering that max forwards 
does the job at some point, nobody spent the time for something else.

Cheers,
Daniel
