I've ported my copyover code, and even made a patch for Circle (pl11
however). It's available from my homepage and probably the Circle ftp site
somewhere. Note that the version with Circle patch in it is version 5.
Next generation: copy all allocated data to shared memory and after reboot
reinitalize all lists, so that not only do players not lose link, but
nothing happens to the game world :) (This of course is only possible as
long as none of the structures change size).
Or, let the memory/string manager allocated data in shared memory directly
:)
When data does not have to be loaded, but just the executable, it'll just
take a second to reboot :)
