Does this not have the same issue as #1034 , the weak_handler is not accessible within the tornado_processor inner func https://github.com/getsentry/sentry-python/blob/master/sentry_sdk/integrations/tornado.py#L135

Good catch, but I believe self will stick around for the duration of the request handler invocation, which sticks around for the duration of the response streaming, so it should be fine afaict

let me add a test

I don't think the test you added covers that case since that request raises an exception and so triggers the error handler.
I would create another test to check if the request body exists when the request doesn't raise an exception and returns a success status code.

Conceptually the exception won't make the request stay around for longer, but you're right it's not the same testcase so I added another one.
