I tried to see how often this was happening, but there's ?another failure mode where it times out, but doesn't say long running test.

However, the query above shows 211 timeouts in the last month, which is a lot.

Any thoughts, @stephentoub? As far as I can tell, your ReadAsync_CancelPendingTask_ThrowsCancellationException test is pretty simple, and CryptoStream's ReadAsync passes the token down to deferred stream.ReadAsync calls. (It can complete synchronously even with the token set to cancelled, but that wouldn't cause a hang).

Is this only failing on mono interpreter legs?
