Touches the filesystem (delete), so requires extra scrutiny.

It feels like instead of *(context->securityOrigin()), you could just say *context->securityOrigin().  The extra parens make me initially expect something sneaky to be going on even though it's pretty straight-forward.

Hungarian notation!?

It is the sanctioned prefix for PassRefPtr when you want to put it into a RefPtr in the function. http://www.webkit.org/coding/RefPtr.html

Tim already pointed out this is the PassRefPtr standard.

What a weird choice. I get the desire to distinguish the name from the actually used one, but I'd use something like "passCallbacks" or "callbacksParam" or "callbacksArg" to make this clear. I will have to ask Darin why he used "prp" in the RefPtr guide.
