Can't defer response from handleMethod:withPath:block:

[ghoover]

I'd like handleMethod:withPath:block: to be able to defer response until after some other asynchronous action has completed.

For example:
handleMethod is called, I pull data from Core Data asynchronously, and finally respond to the HTTP request with respondWithString: (or other).

The problem is that the connection is immediately closed after the end of the block call in handleMethod:withPath:block:. I kind of just assumed it would be possible to do what I was thinking based on the method names and the use of blocks. Is it possible to add an asynchronous group of responses that hold the connection open until I mark done?
