Illustrate the point of graceful shutdown

[dgroomes]

This repo makes a show of implementing graceful shutdown (

wiremock-playground/programmatic/src/main/java/dgroomes/wiremock/WireMockUtil.java

Line 21 in 813721e

public static WireMockConfiguration shutdownGracefully(WireMockConfiguration options) {

) for the underlying Jetty server. But what does that mean? I don't even really know?

From the perspective of a developer using WireMock (or Jetty), what is graceful shutdown useful?

Does it mean I can Ctrl + C to kill WireMock? Does it mean the exit code will be a non-error exit code? Does it mean that Jetty will wait some time to actually let some long request finish instead of killing it before it can finish?
