Thanks pal, I've read it last summer. Now I've been reading Tanembaum's
articles on Amoeba, and also some stuff on Mach, Sprite, V, and Plan 9. I
have quite a good idea what micro-kernels and distributed operating
systems are. AND I'M NOT SAYING HERE A MICRO-KERNEL IS A DISTRIBUTED OS. I
hate to be misinterpreted.

Ah, thanks for the kind words.

Read that? I only made a brief comparison of ONE GENERAL ASPECT, which is
module loading. I know micro-kernels load servers to implement an OS's
interface to binary apps. Maybe that was just a poor comparison.

Anyway, the whole idea was "Is there a way to safely debug modules?".
Sorry if everybody knows this is unfeasible/unportable/un_whatever. That
was just an idea I wanted to share.

Hope you understand now. ;)
