Norman Feske 693d657e6a base-linux: reflect SIGCHLD as Cpu_session signal
With this patch, core responds to SIGCHLD signals of terminating Genode
processes by reflecting these events as exceptions to the CPU session
interface. This way, Genode processes become able to respond to
terminating Genode child processes.
