This test sets up two timers:
- a 100ms recurring timer
- a series of 10 200ms single-shot timers.
After quitLock lets exec() return it then uses a signal
spy to check if the 100ms timer fired at least 17/20
of the times it should.
However there is no guarantee that the 100ms timer
will fire more often than the 200ms timer. If the
native timer callbacks happen at 500ms intervals then
Qt will fire both timers (once) at that interval.
In practice this seems to happen on macOS CI under
system load and/or with the test app napping.
The primary goal for the test is to verify that exec()
returns when it should; we can remove the timer signal
spy.
Remove testQuitLock from BLACKLIST.
