Are DOS issues in scope? How do we prevent untrusted code from just bringing the interpreter to a halt? A smart enough attacker could even block all threads in the current process by finding a task that is usually not time-sliced and making it go on for a very long time. without looking at the Python implementation, I can't remember an example off of the top of my head, but perhaps a large multiplication or search-and-replace in a string.

It seems to me that this is an issue orthogonal to capabilities (though access to mechanisms that regulate it might well be capability-based).

Cheers,

Ben.
