[2] When invoking `accept-process-output', Emacs waits subprocesses'
   output via the system call "select".  When there are some
   operations avaliabe for the process provided to
   `accept-process-output', it returns.  However, the _order_ of the
   read content is not guaranteed to be the same as the process
   output.  It is decided by the arrival of the output.

I have looked at the executing process with the "strace" tool, on
FreeBSD and Linux.  Although the data arrival order may not be
the same as when executing in terminal, the read output is correct.
