    Description

      QNetworkManager's get() method stuck for too many time with qt 5.8.0.
      First call takes long as obvious, but next calls are too long.
      For 4.7.1 repetitive request takes about 0-1 ms.
      For 5.8.0 repetitive request takes about 12-13ms on linux and 60ms on android.

      This BUG kills interactivity for any application which send http requests from main thread.

      To demonstrate, run attached app using qt-4.7.1 and qt-5.8.0.
