Threads cannot be opened in the direct, traditional fashion in App Engine,
due to runtime sandbox restrictions
<https://cloud.google.com/appengine/docs/java/runtime?hl=en>. You can use
com.google.appengine.api.ThreadManager
<https://cloud.google.com/appengine/docs/java/javadoc/com/google/appengine/api/ThreadManager>
to spawn threads. Read the "Threads" section of the first linked doc to
see more details. Be aware that they will need to join before the HTTP
response is finally sent and the servlet method terminates.
