For regular App Engine, threads are allowed/not allowed depending on the
type of instance the code is currently running on. See the table here:
https://cloud.google.com/appengine/docs/java/modules/#scaling_types and
look at the entry marked "Background Threads." There's also a limit on the
number of threads you can run: http://stackoverflow.com/a/20896720

For managed VMs, you can essentially run anything you want, however you
want it. If you want to open up a ton of threads, that's perfectly fine
within a managed VM. Depending on your use case, you may not be able the
replicate the same in a regular instance.
