The SRM does not zero memory across warm reboots, at least.

This gives us opportunities to screw things up royally, like the
problem that jb was seeing with newly installed bootblocks working
until a cold boot.

Not zeroing also allows all sorts of opportunities for cool hacks.
Like leaving the buffer cache warm in ram, rebooting a box, and not
needing to read the data from back from disk.  Have a look at
