  Log:
  Maintain the lock on the vnode for most of exec_elfN_imgact().
  Specifically, it is required for the I/O that may be performed by
  elfN_load_section().
  
  Avoid an obscure deadlock in the a.out, elf, and gzip image
  activators.  Add a comment describing why the deadlock does not occur
  in the common case and how it might occur in less usual circumstances.
  
  Eliminate an unused variable from exec_aout_imgact().
