------------------------------+------------------------------
 When I run a chutney network with an empty bwfile, the network seems to
 fail more often.

 We should either:
 * fix this bug on tor clients, or
 * make authorities never vote zero bandwidths:
   * make the minimum bandwidth 1, or
   * drop relays with zero bandwidths from the consensus.

 This blocks adding a bwfile test to make test-network-all in #26803
