And to date there hasn't really been any compelling reason to issue tiny
patch security-updated kernels, 'cause you have to reboot anyway, right?
 But as the technology improves, more opportunities arise.

I recall deploying some sort of hack workaround for the vmsplice exploit
a while back on a whole bunch of machines (Fedora or downstreams) that
were going to need a reboot scheduled up to a week in the future.  This
kind of technology would have been really swell to have then.

Lots of reasons to not want to reboot machines - most of the arguments
for supporting laptop suspend would fit.  Some of them may fall into the
"protecting users from themselves" category, but that's not a bad thing
either.
