Unwind-Protect and Jumping into the Abyss

[liberte at cs.uiuc.edu]

I'd never heard of ContinueUnwind - do any other languages support it?

What about nested unwind protect blocks?  If an outer unwind protect does
a continue unwind, do inner protected blocks get executed first? I guess
that would make sense, but perhaps not always.  What if the inner protected
block closed something that needs to remain open in order to continue
the execution?
