That's only the case with interactive shells! In non-interactive
shell sessions (typically a script), background process are still
launched with the same process group as the parent script.  Since
the SIGINT is propagated to all processes sharing the foreground
process group ID, this should explain why qemu is receiving the
SIGINT as well.
