When creating Helloworld extension , got the following error message after F5
cannot connect to runtime process (timeout after 3000ms)

Copied from original issue: microsoft/vscode#893

I suspect that a timeout of 3000ms is just not enough to launch and attach to the extension host process.

However in VS Code 0.10.x I did not make the timeout longer because the same timeout is used when VS Code polls for a terminated extension host process. So making it longer would mean that you cannot start a new debug session, because VS Code is still waiting for the old session to timeout.

For the next release we plan to eliminate the polling which makes it possible to increase the attach timeout to whatever we need. The associated issue is this: microsoft/vscode#855
