Hmmm... The script is definitely timing out. PHP is just having trouble
exiting out cleanly. zend_timeout() does one of two things: it either
calls exit() to terminate the process immediately, or it does a
longjmp() to a bailout point set earlier. Usually it's the latter.
Whatever it's doing it's fubar...

One thing to try is set time limit to 0 (i.e. infinite). At least then
PHP wouldn't fall into this trap.
