You can't create a new thread, but you can have multiple concurrent requests if you say your app is thread safe in appengine-web.xml, which means that your code will be running with multiple threads.
I must admit that I just assumed all the services provided by App Engine to be thread safe. If any are not I would expect this to be flagged up in the documentation. If they weren't we would have seen lots of complaints about applications getting screwed up in interesting and unexpected ways, so I'll take a bet at pretty good odds that they *are *thread safe...
