You can use mod_wsgi to run processes outside of httpd. (WSGIDaemonProcess) Also, I think it is fair to say that it is mod_wsgi's responsibility to isolate Python environments from complications related to graceful restart, but perhaps the author would disagree. Maybe there are mod_wsgi fixes you're not running with which are applicable. I have not observed any problems with mod_wsgi's daemon mode and graceful restart. See http://emptyhammock.com/projects/info/pyweb/index.html for various notes on using httpd's mod_proxy in front of Python WSGI-ish applications. -- Born in Roswell... married an alien... http://emptyhammock.com/
