v2-ci / unit-tests (push) Has been cancelled
ci: concurrent-write test's held write hit the fixed 5 s write cap under CI timefactor
A_queued_write_older_than_the_budget_is_failed_BadTimeout_instead_of_written_late
failed hosted runs 2215 (7ec5b95d) and 2260 (8ef5adc6) at
"(await inFlight).Success should be True but was False", after 7 s each time.
It is not load: it fails on an idle machine with AKKA_TEST_TIMEFACTOR=3, the
value v2-ci sets, and passes with 1.

Akka's AwaitCondition with no interval polls every max/10 of the dilated
budget: PresenceBudget 15 s x 3 = 45 s, so a 4.5 s sleep after a first poll
that runs before the pool has entered the write. The held write is bounded by
DriverInstanceActor.RunWriteAsync's fixed, undilated 5 s
CancellationTokenSource, so 4.5 s of polling plus the test's 600 ms settle
cancelled it ("write timeout") before ReleaseWrites(). The sibling tests that
hold a write took 7 s for the same reason and passed only by margin.

All eight AwaitCondition calls in the class now go through
AwaitWritesEntered, which polls every 20 ms. The budget (PresenceBudget)
and every assertion are unchanged.

Local, AKKA_TEST_TIMEFACTOR=3: before 6/7 (this test failing, 7 s); after
7/7 in three runs, test 3 s.
