Is there a way to get the status of the mod_wsgi daemon processes and threads? Something like apache's server status page.
My server's taking a while to respond sometimes and I want to see if it's because all the daemon threads are busy.

You are better off following the mod_wsgi mailing list and asking about what is possible there.
