---------------------------------+--------------------
When TorCtl calls filter(), it often re-uses the iterable multiple times.
But python iterables only yield each item once.
To fix this, we need to turn iterables we want to re-use into a list,
using list(filter()).
This might just be why a lot of nodes remain unmeasured, or measurement is
unreliable. In our test network, it seems to have caused only 5-7/15 nodes
to be measured.
