There was a problem hiding this comment.
One comment, but looks good otherwise.
If I understand correctly, ctrl-c on the terminal will send SIGINT to all the processes attached to the terminal: both tracerunner and bpftrace. Upon reception, tracerunner will ignore it at first and bpftrace will exit gracefully. When received a second time, tracerunner will kill bpftrace.
I wanted to test it, but I couldn't build the docker image (make image/build) because of the ARG before FROM. It seems to be moby/moby#31352. I am trying to upgrade...

@alban found this bug, sending a fix.
The problem is that after switching to tracerunner the tty didn't work as expected because the signals where not handled.
