Yes, I will do that tomorrow morning.

@martincostello Could you please re-run the build / windows-latest step?

[xUnit.net 00:00:02.90] Polly.Specs.Utilities.SystemClockSpecs.SleepAsync_ShouldThrow_WhenCancellationRequested [FAIL]

This test seems a bit flaky :(

[martincostello]

You don't have to ask any time that happens, I'll just do it anyway, as otherwise it's unmergeable.

@martincostello , @martintmk What do you guys think, would it make sense to implement the same for hedging?
