I'm not a heavy watchdog user so don't know, but I made it catch both. (I think
the cgroups stuff sends sigterm and the OOM killer sends sigkill, so this
wouldn't affect either anyway. And a bad lock or driver or the scheduler going
out to lunch due to some variant of swap thrashing isn't any of them. :)
