Brain Dump #1

I've been pondering that for a few days now. If Erlang had a safe
mode, where processes can be boxed in, it might be possible to do
some more interesting programming. But then again, maybe not.
I have never used the safe Perl or safe Tcl functions to run boxed
code, nor have I ever used boxed Java (except safe for a handful of
applets back in '97/'98). That may very well be a feature not worth
One problem is definately the limit on the number of nodes. 200
nodes doesn't go very far on the public internet.
I think time would be better spent ensuring that binary_to_term/1
doesn't do strange stuff when it gets an unexpected binary (stack
smashing attacks, etc.).
