--- Comment #2 from Ben Nham <nham at apple.com> ---
The UIProcess responds to the WebProcessProxy::GetNetworkProcessConnection message by turning around and sending a sync NetworkProcess::CreateNetworkConnectionToWebProcess message to NetworkProcess. So basically the sync call to WebProcessProxy::GetNetworkProcessConnection in WebProcess ends up blocking on the main threads of both UIProcess and NetworkProcess.
