 If you mean "use ajax for parallel requests" then that introduces new
 problems.  Ajax has a security model that restricts requests to the same
 domain only.

 If you mean "use ajax and proxy connections through wordpress' WP_HTTP
 classes" then that would only work when then action was initiated from a
 browser.  Actions initiated from crons  would not have access to this.
 These requests would also compete with other ajax requests in the browser.
 There is a maximum number of simultaneous ajax requests, too, that differs
 per browser (I believe the average right now is 8).

 As you've pointed out, curl+php does support this with curl_multi_*
 functions http://us.php.net/manual/en/function.curl-multi-init.php

 I agree that this would be cool to have, but it's not something that is
 supported by all of the WP_HTTP implementations (as dd32 said).  I don't
 think this can be done properly.
