WSGI middleware to measure the memory footprint of GAE Python applications.
The apptrace package provides a WSGI middleware for tracking memory usage in Google App Engine Python applications.
Since apptrace is meant for development and debugging purposes only, it works with the development appserver of the Google App Engine Python SDK and TyphoonAE. It will definitely not work on the GAE production environment.
