I think this discussion is not about Qt Creator *freezing* - at least
that is not what happens on my end. It about the fact that while Qt
Creator window stays responsive, it will not allow the project to be
build (that is: "Run qmake", "Rebuild", "Clear" are all grayed out,
and we can't click them. Same goes for keyboard shortcuts related to
project building). So, the thread is doing fine, Qt Creator works, the
issue is that we are forced to wait until build configuration finishes
before we are allowed to build. If the build command could be queued,
it would be much more convenient.

Hope it helps,
Tom
