The 'tee' is running concurrent with your script and may write before/after
your process (depends on OS scheduling).

In an answer to Srikanth about the role of $| and OS it should be noted
that all this variable does is cancel the buffering of the stdio library
(which is handled in the application). It offers a subset of the options
in setvbuf(3) standard C library function and so has no effect on the
OS kernel.
