 More debug notes:
 
   - My system is not fully utilized wrt. CPU/MEM/BW; an odd thing is that it
     seems to work fine to run multiple onion-grab instances as separate
     commands, e.g., 3x `-w 280` to get up to ~225 Mbps utilization (max).
-    Adding a fourth instance gets me into the same problem as documented above.
   - Tinkering with with options in http.Transport doesn't seem help.
   - Using multiple http.Client doesn't help (e.g., one per worker)
   - An odd thing is that after errors, it appears that only DNS is dead.  E.g.,
     `curl https://www.rgdd.se` fails while `curl --resolve
     www.rgdd.se:443:213.164.207.87` succeeds.  Replacing the system's DNS with a
-    local unbound process doesn't seem to help though.
