inputhook: make PyQt4 plays nicer with pyreadline...

inputhook: make PyQt4 plays nicer with pyreadline PyQt4's own input hook is not really appropriate when PyReadline is active (and possibly other readline packages running the PyOS_InputHook repeatedly). Arguably this should be fixed in PyQt4 itself, but in the meantime we can install a local hook which does the Qt event loop processing in a less aggressive way.
