Revert "Restore Qt 4.6 behaviour: exec() always enters the event loop."

This reverts commit 2e72a8b19ea6c674fb4777860dac50faa5d387e6.

The behavour in Qt 4.6 was wrong.  And even if it was not documented,
it is too late to change the behaviour back at this point.

The tests for QEventLoop and QCoreApplication have not been reverted
