How about an open mode of O_NOSYNC that would mean that the file is
temporary and there is no need to flush the buffers to disk except
when the space must be re-used.  This should automatically be set
for pipes and for blocks whose file has been deleted before closing.
Perhaps the mode should be inherited from the directory also.  How
much system time is wasted flushing buffers to /tmp that nothing
ever intends to re-use?
