Luckly we have wrapped the posix code into an custom wrapper,
thus using AmigaOS own highly effecient memory management.

Our "kernel" is built for low memory systems,
and the memory mangement is highly tested and stable.

Then again this might just be junk compared to modern *nix kernel,
with hardware ecc support etc..

We have no memory protection, thus highly effective 'debugging'.
Mess with the memory and you get an total non recoverable crash.

Indeed, I'll lack good tools to realy stress
test things in production enviroment.

Then you must also make sure this is not
an result of an external source.

Interesting dicussion, I guess I'm out of my knownlage now.
So I step back.
