>Description:

Sometimes the twe driver will generate a warning like the following
on shutdown:

  Uptime: 2m10s
  twe0: Cannot delete unit. error = 16
  Rebooting...

This appears not to be a problem, but the warning is somewhat alarming
and might confuse users (like me -- maybe it is a problem).  If this
warning isn't an error condition, it should not be printed unless
verbose output is requested.
