If you set the Content-Length HTTP header in your "Thank You For Registering" response, then the browser should close the connection after the specified number of bytes are received. This leaves the server side process running (assuming that ignore_user_abort is set) so it can finish working without making the end user wait.

Of course you will need to calculate the size of your response content before rendering the headers, but that's pretty easy for short responses (write output to a string, call strlen(), call header(), render string).

This approach has the advantage of not forcing you to manage a "front end" queue, and although you may need to do some work on the back end to prevent racing HTTP child processes from stepping on each other, that's something you needed to do already, anyway.
