[Bug 314436] Re: package-diff can generate infinite output

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

Here's a straightforward recipe that shows off the problem. Run this in an empty scratch directory. mkdir a b for x in `seq 1 8`; do mkdir b/$x; for y in `seq 1 8`; do ln -s ../$(($y + 1)) b/$x/$y; done; done diff -Nru a b -- package-diff can generate infinite output
