[Interest] Process isolation with Qt - how to communicate with child processes

[Etienne Sandré-Chardonnal]

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

> E.g. you can use QSocketNotifier to let QEventLoop do polling for you.
