[tor-dev] Reducing initial onion descriptor upload delay (down to 0s?)

[Razvan Dragomirescu]

I've just tried the patch from ticket 20082 and it works great for me. I
was actually wondering why it was taking so long for a ephemeral hidden
service to get registered in my SIM4Things project (I register an ephemeral
service first to get Tor to setup the introduction points, then re-register
it a la OnionBalance with a new identity). It's definitely a great
improvement for my project!
