...caused runtime restart
There were some situations where the package list could be set
with process stats when it shouldn't. Not sure if this is causing
the problem, since there is no repro.
Also some improvements to debug output -- new commands to clear
all stats, print full details of stats, and print a one-day
summary (which should match what the UI shows).
