  Log:
  SVN rev 198853 on 2009-11-03 12:52:35Z by kib
  
  If socket buffer space appears to be lower then sum of count of already
  prepared bytes and next portion of transfer, inner loop of kern_sendfile()
  aborts, not preparing next mbuf for socket buffer, and not modifying
  any outer loop invariants. The thread loops in the outer loop forever.
  
  Instead of breaking from inner loop, prepare only bytes that fit into
  the socket buffer space.
