I don't see how doing ar << *dockBarPtr would address this.

I'm guessing that this is a windows program as I've had similar problems.
I ended up creating a custom windows message. I post the message to
the main window.  When the UI thread gets the message, it does serialization
or whatever you want on the UI thread.  Of course this has nothing to
do with serialization.
