That makes sense. I'll add that to the test mix. I gather that you're
using something like liburi-fetch-perl, yes? A little reading tells me
that sites more often reject curl and wget, compared with fetch and
lynx. But I'll use whatever you're using for basic HTML.

Sorry, I wasn't clear. I meant that I might have been overloading my Tor
client with too many simultaneous circuits.

Again, I'm talking about effects on my client and the VM it's in, not on
Tor relays or websites.

Agreed. But I would like a response about fetch (liburi-fetch-perl?).
