Now I'm using url-queue-retrieve where the default number of
parallel processes is 6, so if the queue works well then there
shouldn't be too many subprocesses.

I tried url-queue-retrieve with url-queue-parallel-processes set
to 1 and there was no 'not running' error then.
But during fetching the urls there were lots of open processes,
when I checked list-processes, so either the connections linger,
or the 'open' state of network processes in list-processes
means something else than an open network connection.
This is with url-queue-parallel-processes set to 1 and when
I started the queue list-processes was empty:
