 During update to WP4.2.1 wp_tempnam gets into a loop when filename is
 ".maintanance".
 Error logged is: Allowed memory size of 268435456 bytes exhausted (tried
 to allocate 65488 bytes) in /home/pi/wordpress/wp-admin/includes/file.php
 on line 159

 I could solve this by adding the following:

         if ( ! $temp_filename ) {
 /** begin added code **/
 if (dirname ($filename) == "/")
         return dirname ($dir . "x") . $filename;
 else
 /** end added code **/
                 return wp_tempnam( dirname( $filename ), $dir );
         }
