aquatic_bench: test multiple threads at once, with disappointing results

Browse source 
DashMap doesn't scale as well as I had hoped. Only the scrape
handler performed somewhat better with more threads, since it
doesn't exlusively lock the torrent map. The announce and connect
handlers, however, gained barely nothing from more threads.
