      Description

      in examples/network/downloadmanager the following calls stall and eat up all CPU:
      ./downloadmanager http://www.dailykos.com
      ./downloadmanager http://www.bestblackhatforum.com

      I think I could find more examples if needed.

      strange thing is, the backtrace is the event loop. Qt seems to sit in a tight loop polling a file descriptor.

      Apparently a regression from 4.8
