I'm not an expert but certainly there are long standing issues with 
DejaGNU, well beyond perfornance, right? I remember Mark Mitchell doing 
some work in this area which, as far as I can remember, had nothing to 
do with performance per se. And, well, some of these issues are obvious 
to explain, like not being able to check for *duplicate* error messages. 
I remember briefly discussing this with Dodji in Manchester.

Just wanted to make sure this kind of public discussion isn't completely 
suppressed.

Paolo.
