== info ==

The server needs to be multithreaded to be capable of simulating catplosions and
fluid dynamics.

== some notes ==
=== jobs and their data access patterns ===
* gravity, rw on complete map
* fluid, rw on complete map 
* vegetation, rw on complete map, slowakei
* monster, r on complete map, rw on monster mobiles
* patzfinding, r on complete map 
* lighting, r on complete map, w on lighting infos
* weather, r on complete map, w on weather infos
* collision/movement, r on complete map, w on mobiles

=== questions ===
* is it necessary to keep consistens snapshots of the data over multiple steps?
* backbuffer or copied border?
