We have also @Suspend in JAX-RS that can't use Future return type as
it'll block the client.
Timeout:
1) I do not see asyncTimeout in @WebServlet - was it proposed and dropped?
2) What time period will it define?
a) to cancel if not started, or
b) cancel after running for that long, or
c) cancel of a combination of a) and b) is too long?
Anything other than a) might not be even possible in XA transactions.
