Make a url-future (basically a defstruct):
(make-url-future :value (lambda () (calculation goes here))
:callback (lambda (future) (use future on success))
:errorback (lambda (future &rest error) (error handler)))
Then either call it with url-future-call or cancel it with
url-future-cancel. Generally the functions will return the
future itself, not the value it holds. Also the functions will
throw a url-future-already-done error if you try to call or cancel
a future more than once.
So, to get the value:
(when (url-future-completed-p future) (url-future-value future))
See url-future-tests and the code below for further details.
