sequential qerying active servers takes too long

This was reported on IRC:

10:40 < Demitar:#ember>Does ember query servers sequentially? Or is that perhaps all wrapped up in eris? (I'm asking as it takes forever to get the
interesting servers up in the list, and I've noticed there's a whole host of unreachable servers out there.)

I've had the same result and did some testing while talking to Al:

11:14 < pwrcycle:#cyphesis>here's the timestamps..
11:15 < pwrcycle:#cyphesis>entered "date" on the server to get a timestamp at the same time Ember queried the first server in the list "SECRET"
11:15 < pwrcycle:#cyphesis>Mon Sep 29 11:11:31 EDT 2008
11:15 < pwrcycle:#cyphesis>i tcpdumped on the 6767 port to watch the data go out to my Ember client:
11:15 < pwrcycle:#cyphesis>11:12:52.259335 IP 64.85.164.54.6767 >

11:16 < pwrcycle:#cyphesis>it was the Silicea server that takes a long time to reply..
11:17 < pwrcycle:#cyphesis>when it shows up, Amber, and llama11 return as active very fast.
