I see this issue in a similar vane to using QThread, when the Trolls/Nokia/TQP (I forget who originally wrote it) wrote up a small but very effective white paper on the proper method of using Qthread, it clarified a ton of questions for many people.

You'd probably get feedback that QThread is "too heavy" and for i/o bound processes one async event loop is enough. (I've been on the rx end of that)

I think my highest of levels approach is correct:

The one caveat to my code, is if you don't need synchronous requests (regrettably, this part of my app requires them) then you can ignore the QEventloop stuff, that is leave lines that references `loop` it out, and you'll have a fully async inline lambda.

You however are asking for a synchronous and this I think is the best way. Feel free to assault the code, (Thiago and others.) I would like Qt to adopt some kind of this pattern.
