That means a file is never created, unless you ask for the name. There's
no chance of left-over temporary files being left behind. QSaveFile also
benefits from this, since the save file is not present on disk until
commit(). Unfortunately, QSaveFile must go through a temporary name
because linkat(2) cannot overwrite -- we need rename(2) for that (for
now).
[ChangeLog][Important Behavior Changes][QTemporaryFile] On Linux,
QTemporaryFile will attempt to create unnamed temporary files. If that
succeeds, open() will return true but exists() will be false. If you
call fileName() or any function that calls it, QTemporaryFile will give
the file a name, so most applications will not see a difference.

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.

On BSD systems (tested on macOS and FreeBSD), you *can* lseek(2) or
ftell(3) on a pipe and get its current position. But QFile will not get
the position when the file is sequential, so we need to return 0.
Technically speaking, we ought to do the same for block devices, but if
you're redirecting stdin, stdout or stderr in the unit test to or from a
block device, you deserve the extra work to add that yourself to the

in fact correct. In contrast, our eyes can make sense of a
QDateTime's reported value quite well, enabling us to see what's
different; and it's possible to at least confirm the plausibility of
2-or-3 am on a spring or autumn day at a plausible transition (or even
to confirm it exactly by consulting suitable web-sites). Also
document the actual transition happening in each case (since I *did*
consult a suitable web-site). So prefer to QCOMPARE(,) two QDateTime
values instead of two 12-digit qint64s.
Where a that would be unsuitable, at least compare the difference to
zero, to make the error easier to understand (except when one of the
twelve-digit numbers consists entirely of 9s; that, for once, actually
is easy to see).
Write various multiples of 3600 as the relevant intelligible whole
