The limit of 10 applies to asynchronous urlfetches in a single request as describe here:
http://code.google.com/appengine/docs/python/urlfetch/asynchronousrequests.html That being said, if a large proportion of your requests are making URLFetch requests and this causes your user facing round trips to be 800ms+, App Engine will not autoscale the number of instances you have running. It's best to move these operations to task queues.
