Issue 99: ImageSegments for smoother upgrades that don't kill sessions?
http://code.google.com/p/seaside/issues/detail?id=99

New issue report by ramon.leon:
Is there a possibility of using ImageSegments to partition out the 
state of a Seaside node so
upgrades can be rolled out to load balanced farms by having the running 
node save and quit and
immediately start up a new version to replace it so users only notice a 
momentary pause but not
have their sessions blown away?  It's one thing to hot upgrade a site 
running in a single image with
VNC or the web interface, but if you're load balancing a whole slew of 
nodes that's just not going to
work. It's much easier to copy out a new image and restart all the nodes.

I don't actually know if this will work, but if ImageSegments can save 
blocks and continuations then
isn't this possible?
