disk file portions with memory segments (that being what Unix's MMAP
does, roughly),

Anyway, I've seen some interesting ideas for plan 9 and inferno, most
of them out of my reach. But I think some of them are easy enough for
me to try them (hope so!).
So I would like to give it a try to

I think russ has added this functionality to his kernel. The sourcecode of his
linuxemu had commented out lines that used special segname with a filename
to map elf-files into memory.

Hi,
I got confused by output redirection, even though I have used it like
a thousand times:
cmd1 | cmd2 | cmd3
this pipes cmd1 stdout to cmd2's stdin and finally cmd2's stdout is
piped to cmd3's stdin. All cmd[1-3] stderr are displayed (presumably)
at the terminal along with cmd3's stdout, right?
If this
is the case, how can I redirect cmd1's stderr to cmd3's stdin instead
of cmd2's? or both?
It's a pipe_line_, not a directed graph. You could write a wrapper to
do what you want quite easily, but expecting a simple, generic shell
notation to do it is asking a bit much. At least, I
see port/fault.c to see what happens on a page fault in the text segment.
Yep, I remember trying to understand that part from a rather
superficial study of the sources. Nemo's commentary will no doubt
prove itself invaluable once again, as soon as I track it down (time
to print a copy). And

I don't know if others have already hit this kind of problematic, but I
was dealing with a fair amount of C code, usable both as a library and
accessible by a shell. Plus debugging needs. So I was, again and again,
writing a wrapper to access a C function from the shell.
So I ended concluding
If you have to go to this level, wouldn't it be better to have a language
for this? You probably wouldn't want this interactively, prototyping aside.

Thanks to everyone for sharing their views on the licensing issue. Quite
a few statements and arguments to think about... Choosing an appropriate
license for a project is even trickier
But when you do something like
cmd1 | cmd2 |[2] cmd3
you get cmd1's stdout piped to cmd2's stdin; but my confusion begins
here: is it cmd1's or cmd2's stderr that gets redirected to cmd3's
stdin? maybe both? my guess is that ...
why guess?
% {echo cmd1 [1=2]} | {echo cmd2 [1=2]} | sed
