Matt Woodrow
In order to do rendering in the GPU process (for bug 218482), we require the ability to do synchronous IPC from web worker threads.
Currently, IPC::Connection supports sending asynchronous messages from any thread, but synchronous messages can only be sent from the main thread.
This allows secondary connections to be created for worker threads, and supports sending sync messages from the creation/owner thread.
For simplicity, receiving of other messages while blocked waiting for a sync message reply isn't supported in this mode.
