If we do, it becomes obvious that the current error handling is not good enough. The request may have made it to the server and the answer will get queued. This means the next command may get the return value from the previous command with suitably puzzling results. Without rewriting large sections of code, its not possible to avoid this problem. It is better to increase the timeout to several seconds giving the server a chance to respond and if it does timeout, hard exit since recovery is not possible with the code base today. I'd be happy to see the structure of this code improved but this quick fix at least stops corrupted builds from happening which has to be a good thing.
