Here's my standard true Itanic story. I know a guy who wrote the sin()
intrinsic. His comment: I do not intend to write cos().
I am working on a python ctypes FFI trampoline for IA-64 Windows. I
find the processor architecture lovely. I am sorry your friend was

Some do.
ARMs are so cheap ... don't jail things, just get another one.
i wasn't aware of that.
so for my arm http/ftp server, you suggest one physical cpu
for each http/ftp connection? how do i route the connections?

i wasn't aware of that [ARM with virtualisation].
it's a little misleading: it's just another option in the
ARM set, and fairly recent at that. whatever it is, yours
probably hasn't got it, but it can take a little while to
work that out.

If you want what a jail does, I still think there are better ways on

Just looking at all the mods people want for jails, these almost seem
like less work.
i don't think so: i think it wouldn't be hard for simple changes
to address it. it's better than pushing the problem to a lower level

To answer #2:
I found sysr1 useful while fiddling with devtrace, because it's a
syscall that does nothing. In addition to providing insights to how

This one sounds like a waste for a system that is so close
to supporting proper jailing

Quite similar here.
