Object leak in logging panel when using threads

[willmcgugan]

I recently tracked down a memory leak in our app, which turned out to be caused by the debug toolbar.

Our Django app launches and destroys a thread in the context of a view (to talk to a websocket server). When that thread writes to logs, debug_toolbar creates a reference to the Thread instance which it never clears. Disabling DEBUG makes no difference.

Essentially this call only clears the view thread, and not any sub-threads that may have been created in the view.

I think you might want to make _records in LoggingPanel a weak key dictionary, if I have understood the code correctly...

so you have any implementation plan with tests?
