merges r31237 from trunk into ruby_1_9_2.

* 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]
