I've experienced the exact same thing. Not only that but some ROMs i've tried with myphone seem to take forever to restore the msgs (1 at a time), while others move much faster (usually about 5 or 6 at a time while watching the status bar). As soon as I get them all downloaded it seems like the HTC messaging 2.5 app starts to choke hard. Wondering if its due to the raw amount of messages. Perhaps even if I didn't restore them once I built up enough if it'd start acting up again. I also have the same problem you describe with the threads not showing up properly.
