Incomplete attempt at actual server for challenge 31
Incomplete attempt at actual server for challenge 31

For reasons that are unclear to me, recover_signature doesn’t work
reliably with this server, unless I limit the number of threads to
something like 6, in which case it is very slow. I think I will work on
other stuff and then come back to this later.
