* The fflush_slowly function is used to flush a file stream and check

* The functionality and calling interface is identical to the fflush()
* function:
*
* "The function fflush forces a write of all user-space buffered
* data for the given output or update stream via the stream's
* underlying write function. The open status of the stream is
* unaffected."
*
* If errors are encountered allow for a pause and retry. This is
* cultural imperialist tourist mode: When English doesn't work try
* loud, slow English.
*
* @param stream.
* The stream to flush If the stream argument is NULL this function
* flushes all open output streams.
* @returns
* Upon successful completion 0 is returned. Otherwise, EOF is
* returned and the global variable errno is set to indicate the
* error.
