Bug Description
The frozen version of curl-4.47 on 16.04 LTS has serious performance regression caused by bug in state machine which is causing a a poll() loop. The symptom of this is high percentage of sys time of a multi threaded process. In my case, as much as half of process time was sys (aka time spent waiting for network IO). curl-4.50 as it is stable in 16.10 does not show this behavior therefore I'd like to request version bump to be able to use LTS with fixed curl.
