You have a point. Though "load" would be pretty arbitrary -- I could
see some load-xxx.escript files that did terrible things while the
other scripts were run. But it would depend on what else is running on
your system. And your system architecture. And your system hardware.
Waiiit a minute, this just got real complicated!

So, don't make decisions unless you have reasonably complete
information, whatever that means :)
