Graceful exit for cleanup of temporary folders

I have noticed temporary files and folders created during "DevMode" and "codeserver" execution, which are never deleted because there is no way to exit the running process gracefully.

Some of the folders seem to be generated by "codeserver" , some others by the GWT compiler , some others by Jetty, etc.

There is also possibility for more temporary folders being be created by custom DevMode launchers, leading to even greater waste of space.

GWT is expected to be cleaning these folders on JVM exit, if it does not already.

Theoretically, GWT Plugin should able to send a graceful termination signal to the running DevMode process.

Would such a feature be desirable ?

Comienza siguiendo cómo el plugin inicia y detiene los procesos de DevMode y codeserver, y después revisa el comportamiento de limpieza descrito en GWT issue 10109. Se considera terminado cuando el proceso en ejecución puede recibir una señal de terminación ordenada y las carpetas temporales creadas por GWT, codeserver, Jetty o launchers personalizados se limpian al salir de la JVM.
