Or; "It's not hard to write RTL code, but *don't* do anything wrong!" ;-)
Well, basically, it's the same problem as with the C64, Atari ST, Amiga, Mac
and many other machines before we got MMUs: The APIs may be incredibly nice and
simple, but a pointer bug can still blow you system sky high. Those machines
were not exactly hard to program, but there were less room for cheating and
generally bad habits, such as ignoring return codes, not releasing used
resources when quitting etc.
