I'd like to supply the patch, I've placed it on my todo list. I will 
probably not finish it before the release,
but since it will probably not be included anyway, it doesn't matter.
I do not know why LTP used SIGINT in the first place. My first thought

Ok sounds reasonable. The nice think about changing timeout to SIGTERM 
would be,
that abort using CTRL+C is clearly distinguishable from a timeout.
