Oh. I thought that ischemia was being used to refer to the actual
suspension period, which is admittedly my fault, but will perhaps be
recurrently the fault of others as well. Anyway, I know that "ischemic
coma" was proffered as a synonym for "reversibly dead" at least once in
the history of cryonics, and I also know that I've seen some attempts
