Eh, yes. As that's the defined behavior. What else would libcurl do?

That's rather pointless since libcurl won't do anything to stalled connections
after 60 seconds, 600 seconds or 6000 seconds even if you call the timeout
action. Unless you set one of the options that will make it care, and then it
should also set the timout...
