I plan to place other temporary files created by KDevelop into the
session temporary directory in the future. For example, KDevelop leaves
behind many temporary kdevelop.* files after exit. Not all KDevelop
tests remove their temporary files on exit. The session temporary
directory use can be wrapped into convenient classes derived from
QTemporaryDir and QTemporaryFile.
