Comment 11 for bug 314436

This happened again today with cordova-cli, twice. I'm going to arrange to kill debdiff after ten minutes, which should provide fairly reasonable headroom for large packages; 99.9% of successful PackageDiffJobs in 2015 finished inside 09:02, with the maximum being 33:31. I'll make it a configuration option so that we can easily tweak it if need be.
