Asynchronous HTTP

I'm commencing an application that will go get a multitude of web
pages. There's been a number of EU applications for HTTP requests.

I like the look of AsyncHTTP.ew. because I can get a number of
requests under way at the same time. But that leads to a limitation of
my understanding of how to process them.

>From the documentation: "Because it is asynchronous you do not simply
call a function which returns a value, you call a procedure to say
that you wish to retrieve a document and when it has been retrieved
you are notified".

That's straightforward, but if I send 10 requests, and they all come
back at about the same time, I presume my handler is going to be
interrupted up to 9 times. Do I somehow have to write re-entrant code
for the handler? Are there any guidelines on how to do this? Or have I
missed a point somewhere?

Thanks,
