exist before this method was invoked, any subsequent invocation
of this method will yield a different file name.</p>

@param  string $prefix prefix before the random number.
@param  string $suffix file extension; include the '.'.
@param  PhingFile $parentDir Directory to create the temporary file in;

@param  boolean $deleteOnExit whether to set the tempfile for deletion on
normal exit.

chances exist that a file with the same name is
created in the time between invoking this method

possible set to true.
