Description Peter Hutterer 2015-10-29 01:29:30 UTC 
We don't use SIGIO right now because it does weird things to the epollfd that libinput exposes and in anyway, libinput is not designed to work inside a signal handler.
The drawback of this is that pointer movement stalls if the server is busy.

We need to find a suitable approach to run libinput in a second thread for dispatch() and pass the events through the SIGIO handler to the server.

fixed in server 1.19 with the input thread
