It would be good to understand the need to explicitly use the Python 2.7 runtime.
Elaborating on the reasoning for specifying the YAML property threadsafe, we must explicitly define this property when using the Python 2.7 runtime per <<a href="https://cloud.google.com/appengine/docs/python/python25/migrate27#appyaml">https://cloud.google.com/appengine/docs/python/python25/migrate27#appyaml</a>>. We define threadsafe to be false because the status server code was written to be run in AppEngine's CGI environment (by <<a href="http://trac.webkit.org/browser/trunk/Tools/QueueStatusServer/main.py?rev=174622#L90">http://trac.webkit.org/browser/trunk/Tools/QueueStatusServer/main.py?rev=174622#L90</a>> and <<a href="https://cloud.google.com/appengine/docs/python/tools/webapp/utilmodule#run_wsgi_app">https://cloud.google.com/appengine/docs/python/tools/webapp/utilmodule#run_wsgi_app</a>>). And AppEngine's CGI programming model handles requests serially per section "Concurrent Requests and WSGI" of <<a href="https://cloud.google.com/appengine/
