Subject: zend_alter_ini_entry threadsave if used in SAPI modules?
From: uwe@thetaphi.de (Uwe Schindler)

I am writing on an extension of the NSAPI SAPI module (see bug #8879) so 
that you can specify some overrides for php.ini entries at execution of a 
script from the webserver (like you can do it in apache).

I want to set the variables with
  zend_alter_ini_entry(..., PHP_INI_SYSTEM, PHP_INI_STAGE_RUNTIME);
but this call have no reference to TSRM.

Can I use it or is it not thread save? e.g. if two requests to the 
webserver on two virtual servers run at the same time and each thread 
overwrites the doc_root property in php.ini can they coexist. Are 
PHP_INI_STAGE_RUNTIME settings only valid for one thread?

Looking at aolserver SAPI, the ini feature is commented out there because 
of thread safety...
