[Interest] QThreadPool - global instance or custom one

[Frank Rueter | OHUfx]

Hi all,

I have started using QThreadPool for the first time and am wondering if 
it's save/recommended to create my own instance of it or to always use 
the global instance?
I.e. the docs all tend to refer to the global instance but they don't 
say anything about creating your own.

Are there any pros and cons?

In my case my app will run inside a host application, so my gut feeling 
says to create my own thread pool so I don't accidentally hijack the 
host application's pool, but I may be wrong?!

Any insight on this?

Cheers,
frank
