Well it doesn't sound like this is something they just started doing. My
PHP extension has been tested on numerous platforms and I have only ever
seen the PHP module initialization / deinitialization routines called
once on startup / shutdown. Even if the actual PHP module is loaded
and unloaded, do you call the (de)initialization routines for each
(unl)load? I'm not sure this issue is the issue I'm seeing.
