How to re-read a bundle once read?

I can use [NSBundle bundleWithPath:<somePath>] to get a bundle
object. Code resources from it get brought in with a "load" method,
and with Leopard I can now "unload" them.

Is there a way to "close" the bundle? The bundle varies over time,
and what I'd like to do is read it, load it, unload it, then re-read
it again.

Thanks,

David
