Description
We had 24 failures in the last 90 days. It either fails with IOException or with NullReferenceException. I was able to reproduce latter in my local runs:
System.Net.Http.Functional.Tests.SocketsHttpHandler_HttpClientHandler_Authentication_Test.Credentials_DomainJoinedServerUsesKerberos_Success [SKIP]
Condition(s) not met: "IsDomainJoinedServerAvailable"
System.NullReferenceException : Object reference not set to an instance of an object.

}from quick debug, it seems like this part of test runs before SerializeToStreamAsync completes. (Complete() sets _waitForCompletion back to null)
await requestStream.WriteAsync(Encoding.UTF8.GetBytes(requestContent));
