      plain QCheckBox e.g. being inserted with qtcreater cannot be rapidly clicked in a row due to a dead time of approx 500ms after being clicked.
      This behaviour was not there in 5.2.2.

      Steps to reproduce:

      • Compile qtbug38319.zip
      • Click checkbox in rapid sequence
      • Note it toggles slower, reports intervals of about 250ms and higher in Qt 5.3 and generates more events (comparing to about 150ms Qt 4, 5.2.1, where it immediately toggles)
