Description
Previously in Qt 6.2.x it was possible to call "kill(getpid(), SIGSTOP);" inside the setChildProcessModifier callback.
This is necessary to start an app suspended, e.g. to later attach a debugger to it.
With 6.4.x ( my guess would be with https://codereview.qt-project.org/c/qt/qtbase/+/417829 ) this hangs in QProcess::start.
FYI: On macOS it still works, its just linux having an issue.
