Even after being moved to `sequential` in
1ce05ad540, `test-regress-GH-897` still
was occasionally flaky on Raspberry Pi devices on CI.
The test is especially sensitive to resource constraints. It failed
reliably on my laptop if I moved it to `parallel` and ran 32 competing
node test processes. Even for a flaky test, that's unusually low. I
typically don't see problems, even for flaky tests, until I get up to
around four times that number.
On a Raspberry Pi, of course, that sensitivity to resource constraints
will manifest much sooner.
This change checks the order of timers firing, rather than the duration
before a timer is fired. This eliminates the sensitivity to resource
constraints. The test can now be moved back to `parallel`. I am able to
run many copies of the test simultaneously without seeing test failures.
