Comment:

 What purpose would setting a transient that expires immediately have?
 Storing a non-expiring transient *does* have its purposes.

 This is the same behavior as caching backends:
 http://us1.php.net/manual/en/function.apc-store.php,
 http://www.php.net/manual/en/memcached.expiration.php,
 http://www.php.net/manual/en/memcache.set.php. For this kind of caching, 0
 means "Store forever" (until deleted or forced out of cache) not "Don't
 store at all."

 Either way, changing this would break existing code.
