D352: chgserver: special handle __version__ in mtimehash (issue5653)

  I will test it on a Mac tomorrow. I think this patch is optional (nice to have).
  
  FB also has some weird reports that suggest demandimport is causing chg to load a mix of old and new modules. So the first two patches are more important in terms of correctness.
