BTW- this exactly what the 'async' library now in GNU ELPA was written to do.
You could use it at least as a first approximation.

Due to expense, I'd recommend collecting as many names to resolve at a time as
you can, and then doing them asynchronously "in batch"; I can think of a few
web pages that would suddenly result in 20-30 Emacsen being forked.
