How to disable APC ... completely?
I need to disable APC, because I think it may be causing issues under load, but when I tried to do this last time (by disabling the extension and restarting Apache), it caused strange things to happen (reading old caches, etc.).
I found out that it's because restarting Apache has no effect on Fast-CGI workers, and that I need to "restart" the workers as well. What is the best (non-destructive) way to do this?
