rootwrap filters. The only exception would be if a user edited them
after installation, but in that case they're responsible for merging in
the updated ones themselves.

Total Pss: 25778 kB
Being the maximum responsible python's heap (the tool doesn't show
who's heap that is, but if I look manually it's /usr/bin/python2.7's
heap).
For reference, a bare python waiting on command line Pss is 2930kB,
984kB due to python heap.
