  SVN rev 186747 on 2009-01-04 19:22:53Z by ed
  
  Remove Giant locking from domains list.
  
  During boot, the domain list is locked with Giant. It is not possible to
  register any protocols after the system has booted, so the lock is only
  used to protect insertion of entries.
  
  There is already a mutex in uipc_domain.c called dom_mtx. Use this mutex
  to lock the list, instead of using Giant. It won't matter anything with
  respect to performance, but we'll never get rid of Giant if we don't
  remove from places where we don't need it.
