  SVN rev 199358 on 2009-11-17 12:09:21Z by kib
  
  MFC r198853:
  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.
