Comment 191 for bug 113201

The hangs under GetProxyForURI are due to exactly this bug. The helper app and bookmark icon bits should be in other Camino bugs, and probably not mentioned here again.

DNS resolution does happen on a background thread, but proxy selection is currently synchronous, so the script waits for the background thread to have completed, making the asynchronicity of the actual resolution somewhat pointless.

What we need to fix this is for someone to help figure out what is causing the mochichrome failure, and then we can look at how to get a patch like this into a 3.0.1. The motivating problem is well-understood, and easy to reproduce.
