[Pulp-dev] Memory consumption on RPM sync

Some results for new remove_duplicates: when isolating that one change
(including all the other performance improvements) it looks like
remove_duplicates went from 40-70% of the total sync runtime to about 10%.
And I think it was also running (unnecessarily) on the initial sync, which
explains why initial sync time dropped by 70-80% while resync only dropped
by about half.
