You weren't prompted? Hmm, could this be because the buffer is
unmodified, even though it doesn't exist?

What's the solution? Should we always force a .swp file to be SaveAs
something else?

Unfortunately, I'm not sure exactly how Vim manages the swap file
process internally. It is something that happens prior to Cream
though, so we'd have to design a way to discover the situation and
then react to it.

Another huge issue that might be solved by investigating this a bit
further is our current hack of turning off swapfiles when
single-session is on.
