I use Tornado ioloop to develop an application, when it comes to http_client.fetch callback, I want to start pdb with import pdb; pdb.set_trace(), but an exception is thrown:
> /home/yiwei.liyw/dsa-engine/src/collect/engine_task.py(52)task_created()
-> print response.body
(Pdb)

What is the best way to use pdb in a Tornado app?
