Process main queue messages by handling the loading in a background queue, and sync it to the main thread periodically, while pausing to wait for the results. This allows the file open dialog to return immediately, and display loading progress on the status bar. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
