Summary
Applies the same stability fix from #759 to
TLruTickCount64PolicyTests.UpdateUpdatesTickCount.The previous implementation used a bare
Task.Delay(1ms)which is unreliable on fast machines — the tick count may not advance in 1ms, causing the test to flake. The fix replaces it with a spin-wait loop that pollsDuration.SinceEpoch().rawuntil it advances past the creation tick count (with a 1-second timeout), matching the pattern established in #759.Changes
