  Exit native bridging early for greater timing accuracy with warnings
  
  This changes native bridging to break one millisecond early so that the more
  accurate timeval calculations done in the generic bridge can be performed using
  the bridge config. Currently the time between exiting native bridging slightly
  late can sometimes cause a large enough discrepancy for warnings to be missed.
  For the record, 1.4 does not attempt to native bridge at all when warnings are
  enabled.
