+ 

+ This script is using a heuristic by analyzing the `ps aux` output because we

+ don't track the list of tickets anywhere (only the corresponding builder knows

+ it's own ticket ID).  It would be risky to expect that the lists of IDs are

+ complete (no lock between the used_ids() and all_ids() calls).  Therefore we
