  SVN rev 218258 on 2011-02-04 09:15:23Z by kib
  
  MFC r218026:
  If more than one thread allocated sf buffers for sendfile(2), and
  each of the threads needs more while current pool of the buffers is
  exhausted, then neither thread can make progress.
  
  Switch to nowait allocations after we got first buffer already.
