Increase timeout when checking for server stop

[sergiodj]

On Ubuntu Impish (development version), we're currently facing a
problem where thin's testsuite fails when it runs on an armhf system.
After some investigation, I noticed that the reason for this failure
was that the server was still running even after the loop on
spec/spec_helper.rb:stop_server.

Given that the loop is actively checking to see if the server has
stopped, I'd like to propose that the timeout be increased from 1
second to 10 seconds. Although I'm not a fan of the
"let's-just-increase-the-timeout" type of solutions, in this
particular case I think it's justified and makes sense (1 second may
indeed be too quick for the server to properly stop).

It seems wrong to me to use a fixed loop like this.

I would suggest using an exponential backoff and then exiting with an error if it's still not dead after several iterations. Otherwise if we just exit and it's still running as you say, it causes the test suite to hang/fail.

I agree that the code is not optimal as is.

My proposal is just to increase the timeout so that we can mitigate the failures we're seeing on armhf. I can't promise I will have the time to work on anything more involved than that, I'm afraid.

Thanks for your effort. We can merge this, however this software is in maintenance mode FYI.
