Google App Engineのタイムアウト時間は約8秒

import time
print "Content-Type: text/plain; charset=UTF-8"
print ""
time.sleep(8)
print "test"

なら上手く表示される

import time
print "Content-Type: text/plain; charset=UTF-8"
print ""
time.sleep(9)
print "test"

だとgoogle3.apphosting.runtime.DeadlineExceededErrorというエラーになって下の警告が出る

※ローカル環境だとどっちも上手くいく
