problem is not on hobbit server side, in which case reducing the concurrency
limit will help. It is actually one specific http server which takes
longer than default 10 second
to respond. I don't want to change the default timeout for all. I was
looking for a {host,service}
specific timeout. Since that does not exist an extension script with
curl for just that one http
server will do the job.
