[Feature Request] ShellStream.Expect - Abort if No Match Found Within a Specified Timeout Period #365

The ShellStream Expect method currently supports a timeout as follows:

public string Expect(Regex regex, TimeSpan timeout)

I believe that when standard output is detected, examining it is a synchronous operation. Consequently, if the standard output consists of thousands of lines then you have to wait for as long as it takes and there is no way to abort:

text = _encoding.GetString(_incoming.ToArray(), 0, _incoming.Count);

I am currently using Expect against a process which can potentially emit thousands of lines to standard output. What I would like is a way to abort Expect if no match is found within a specified period of time.

I am not a C# programmer but am more than happy to conduct some testing and build the project from source if anyone can suggest any changes to make this feature request possible.
