  Per the man page, setvbuf() must be called before any other operation on an open file.

  We use setvbuf() to associate a buffer with a stream, but we have already written
  to the open file.  This works (by chance) on Linux, but fails on other platforms,
  such as OpenSolaris.

  (closes issue #16610)
