Stopping the server while starting it

[kanongil]

I would like to be able to call server.stop() even while it is starting. Currently, it will throw when I try to do this, with no practical way of telling before making the actual call.

The use case is simple: I want to install a SIGINT handler that gracefully stops the server. If it triggers while starting the server, I would like it to abort the start process, and apply the stop process as usual, before calling the server.start() callback with an error.

Note that it should also work if stopped while in the implicit initializing state.

Can't abort the start process fully. Can try in between callbacks.

@hueniverse That was the idea. I guess it would also work if the stop is deferred until the start is completely finished.

Ok, I decided to create an addon to handle my use case, making this request somewhat redundant. See https://github.com/kanongil/exiting if you are interested.

Changed the assertion to a callback error. While this is a breaking change, it should not cause issues as existing code should already be handling errors on the callback.
