[development] Tmp directory

[Darrel O'Pry]

Just a note for developers who write modules that create temporary files...

I've found that a register_shutdown_function('file_delete',
realpath($path_to_file)) is pretty dependable for cleaning up... note the
use of realpath, it's necessary for shutdown functions
and file_delete has the file_exists check in it to prevent errors in the
shutdown phase..
