This is an example of a common race between "begin" and other probes.
Or at least, there used to be a race. Now, begin probes are strictly
done first, and kprobes etc. are only registered afterward.
What could work here even better is an added timer probe that is bound
to run while the kprobes are active, and thus trigger sys_open soon:
probe timer.ms(500) { system ("cat DOESNOTEXIST") }
