Maybe, depending on how many they are and how old are we talking about.
How much cruft is there? Maybe the fact that we don't autoabandon
anymore is a relevant factor?

Looking at Nova time to merge (not the client, since clients are not
analyzed individually), the median is over 10 days (the mean wait is
29). But if you look at the trends of time to way for reviewers, they've
been trending down for 3 quarters in a row (both, average and median)
while time to wait for submitter is trending up.

Does it make sense to purge old stuff regularly so we have a better
overview? Or maybe we should chart a distribution of age of proposed
changesets, too in order to get a better understanding of where the
outliers are?
