What is default timeout value of RestSharp RestClient?

RestSharp is using HttpWebRequest under the hood, which has a default timeout of 100 seconds.

At least some versions of RestSharp (I'm looking at 106.6.10) will use an explicitly set Timeout value when using the async requests, but do not provide a default.

This is because:

The Timeout property has no effect on asynchronous requests made with the BeginGetResponse or BeginGetRequestStream method.
