Context Preservation on Error
-----------------------------
At the end of a request, the request context is popped and all data
associated with it is destroyed. If an error occurs during development,
it is useful to delay destroying the data for debugging purposes.
When the development server is running in development mode (the
``--env`` option is set to ``'development'``), the error and data will
be preserved and shown in the interactive debugger.
This behavior can be controlled with the
:data:`PRESERVE_CONTEXT_ON_EXCEPTION` config. As described above, it
defaults to ``True`` in the development environment.
Do not enable :data:`PRESERVE_CONTEXT_ON_EXCEPTION` in production, as it
will cause your application to leak memory on exceptions.
