This is probably a superstitious/religious belief, I do not like polling
due to the latency/overhead tradeoff that you have to make anyway. Here I
need fairly low latency (about 50ms) so the polling should be at that
interval at most.

Also, I would bet that QSocketNotifier does not work with stdin, but I may
be wrong.

Why do you want to avoid polling? It's quite natural thing when working
