By default, Pdb sets a handler for the SIGINT signal (which is sent when the
user presses Ctrl-C on the console) when you give a ``continue`` command.
This allows you to break into the debugger again by pressing Ctrl-C. If you
want Pdb not to touch the SIGINT handler, set *nosigint* tot true.

import pdb; pdb.Pdb(skip=['django.*']).set_trace()
