g-RPC: Errors in the Chat Exercise

If you haven't concluded the Chat exercise from last week please do so.
Also, once it's working try to add some errors into the g-RPC features, so that you become familiar with common problems:

What happens if the server is disconnected and a client tries to connect?
What happens if a client connects to the wrong port? or the wrong IP address?
What happens if a server crashes while executing a service call?

Threads and Synchronization

Implement a thread pool so that:

The thread pool ThrPool é initialised with a set of N thread.
Applications submit ThrWork delegates for assynchronous execution using the AssyncInvoke method.
The invocation request are placed in a circular buffer.
Free threads can perform requests. If there are no requests, the threads are blocked.
When a thread takes a request from the buffer, it runs it and then tries again to remove another request.

Base your solution on the code in exercicio-3.cs.
