Yes, but you'll still have to call MHD functions inside of the access
handler callback (MHD_queue_response).  Now, you don't have to do it
upon the first time the access handler is invoked; you can just return
MHD_YES and do it "some other time" (if you're using external select).
If you're using a thread per connection model, you can also just block
until you have at least the status code and response headers.

Happy hacking!
