I have attached my first attempt. There are two problems with it:
- DNS lookups are still synchronous. It seems we would need an
external library like GNU adns for that.
That means it fixes only one problem out of two. But it would
still be useful.
- There is no protocol for letting the callback know that retrieval
failed. Without this patch, the caller would immediately get an
error, but now the error is signalled in the sentinel. One solution
would be to introduce an :error argument to the callback, similar to
the :redirect one.
Is that too risky for now?
