Uniform probability does not apply to real life !

I've always been puzzled that, quite often, a package is totally silent for a long while (say a month or two), and suddenly, you get two or three bug reports the very same day, distant from any release or transition to testing. I've seen that mostly with libqt4-ruby and pmount. This seems to be rather general: it really looks like events of our lives don't even remotely follow uniform probabilities.

I've had a recent confirmation with ctioga, a project of my own. I just need to decide to release a new version to realize just afterwards that I've got many more features to add (not less than 20 significants commits since the release a week ago !)... Life is not linear ! (and I won't complain).
