Isn't that what oberon "system" modules are for, escaping in emergency...

Since most operating systems are written in C, and C has nothing like what
Sail had, how does C allow one to tap into processes without being a full
fledged Sail language...

i.e. Oberon is very similar in functionality to C, but at a slightly
higher level.. and Oberon has the "system" escape capability...

So are we saying that even with the System module capability or "unsafe"..
one can still not create a linux (actually BSD) like operating system?
What is oberon lacking if so?

C has something for processes that Oberon currently doesn't?
