First, the scenario you describe explicitly includes death, and as such falls under the 'embellishments' exception.

You're going to die (or at least cease) eventually, unless our understanding of physics changes significantly. Eventually, you'll run out of negentropy to run your thoughts. My scenario only changes what happens between then and now.

Failing that, you can just be tortured eternally, with no chance of escape (no chance of escape is unphysical, but so is no chance of death). Even if the torture becomes boring (and there may be ways around that), an eternity of boredom, with no chance to succeed any at any goal, seems worse than death to me.
