But generally it can be useful too. I'm well aware, however I think even if this flag did nothing but generate a warning it would be useful in both encouraging extension maintainers to verify the TS of their extensions and informing people when they try to use extensions in that environment. Perhaps it would be best if there were a few flags ZEND_THREAD_SAFE, ZEND_THREAD_UNSAFE, ZEND_TS_UNKNOWN. Compiling PHP with TS enabled and UNKNOWN extensions will generate a warning "this might be unstable", trying to use PHP threaded with UNSAFE extension would just blow up. By default all extensions would be set to TS_UNKNOWN and changed as maintainers can do it. John
