Linux's built-in system to manage out-of-memory (OOM) errors is unreliable and non-informative, even if it kicks in (and if often it does too late, when the machine is already unresponsive) there's no easy way to tell that a process on a remote machine was terminated because it was using too much memory. With `earlyoom` we bypass Linux's OOM management and have better control over what's printed to screen in case of error.
