It's possible to call zend_bailout if EG(timeout) is set in UNBLOCK_INTERRUPTIONS macro. But it doesn't solve main problem - it is not safe to just skip the stack - even PHP use locks (TSRM) and its memory allocator also use malloc/realloc/free which use locks, so it isn't safe. External libraries uses memory structures which can't be freed if paritialy modified (because SIGPROF stops modification in the middle). Trying to free them by PHP resource mechanism can cause SIGSEGV, busy loops etc. Not freeing them we loose memory ... I strongly recommend to stop using zend_bailout on timeouts (it's better to exit - it will not hang ;) regards, Wojtek -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
