  Modified files:
    sys/kern             kern_fork.c 
  Log:
  Move a vref call outside of proc locks and Giant.  By virtue of the fact
  that we (p1) are currently running, we hold a reference on p_textvp which
  means the vnode cannot go away.  p2 cannot run yet (and hence cannot exit)
  so this should be safe to do at this point.  As a bonus, it removes a
  block of under-Giant code that was there to support the vref.
