Some questions about a recoverable ram disk that survives crashes though.
Assuming that before a program crashed, it wrote to the ram area 
occupied by the ram disk. What consequences would this have on the
ram disk itself after the guru? Unless the ram memory has been
write protected, wouldn't this result in inconsisten ram disk data?
