Description of problem: DeleteTaskAfter uses atime to determine when a task is deleted. Administrative scripts may access tasks for various reasons, thus updating the atime. Since retrace-server-interact updates the mtime of the task, could DeleteTaskAfter rely on mtime instead of atime?
Fixed in upstream commit 6976d3847b6d934b25bb05e500830fdbdd2c4d17 Author: Michal Toman <mtoman> Date: Mon May 27 15:37:05 2013 +0200 use mtime instead of atime in RetraceTask.get_age()
