I asked Sascha on IRC #php.de and his answer was "Good question. It might have todo with the lifetime of PS(mod_data)." If so, it's clear. If not, there's no reason on running GC at a time where the user definetly notices the (often negliable) delay. But well, there's a lot of "if's" and I just wanna know. Someone with detailed knowledge of the internals should be able to answer my questions: - is a PHP_RSHUTDOWN_FUNCTION() delay "visible" to the user? - what about the lifetime of PS(mod_data), can one still access it from within the PHP_RSHUTDOWN_FUNCTION()? > Anyway, with user defined handlers, you can gc at shutdown w/o > changing PHP C source. Create empty gc function and use If it's possible to run GC on shutdown there's no reason to delay the delivery of php script result by running GC on session start. Ulf
