Do not file without a reproducer, because the only new in QEventLoop's 
constructor is the QEventLoopPrivate, so that issue makes it look like the 
whole QEventLoop got leaked, which can't happen because it is a stack 
variable.

The most likely scenario is that the application exited without waiting for 
all its threads to exit.
