It caches all the data which was pulled out from the resp. language support 
plugin. You could understand it as parser cache -- it contains all the 
information about the bits and pieces in your source code.

It is cached to *not* require a full re-parser of your session each time you 
fire up KDevelop, obviously.

If your session crashes, you'll get that popup asking you whether you want to 
clean your cache. Clicking yes here will wipe the DUChain cache (i.e. 
~/.cache/kdevduchain/kdevelop-$SESSIONHASH).

Hope that helps,
