killes reports that there are a bunch of packaging errors in the d.o watchdog like this:

"ERROR: Can't chdir(/tmp/package/tag)"

The script creates this directory for itself. I don't really know how that could fail, unless the script is taking so long to run that there's a race when two instances are running simultaneously...

I guess we should add some kind of locking to the script so that if it starts up while an older instance is still running, it just
immediately bails.
