This rather dodgy bit of code

.sub main
$S0 = read $P1, 1
end
.end

Causes a crash, instead of raising an exception.

Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000

as probably any other IO opcode. Proper error handling for IO is much
work and a lot of fun.

Patches welcome.

These were things I wanted to do quite a while ago, but then I got a
new job, moved too a new town, had no connection to the internet. At
the moment I work through a huge backlog of mails and try to get
familar with the recent changes of the code. So don't hold your
breath.
