  New Revision: 31237

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=31237

  Log:
    * io.c (rb_io_syswrite): While local FS writes are usually
      buffered, the buffers can be full or the file opened with
      O_SYNC. IO#syswrite can also be used on blocking IOs
      (pipe/socket) just like IO#write.
      The patch is written by Eric Wong. [ruby-core:35554]
