I think, that this is caused by my hack for R_get_location_with_*(),
which makes possible to quit this function from module. It is done so,
that the xdriver is sending info 'nothing happened' to the module and
the module respondes 'go on'. This works in loop and consumes
processor time and everything becomes slow.
