Comment 9 for bug 518512

Hi Brian,

I'm actually not really sure what the root cause of the problem is. If I
run the exact same php/gearman script with the exact same v. of gearman and
php-gearman, but on an ubuntu machine, it works fine. But it breaks on
debian. If I knew what the root cause was and was able to reproduce it
consistently across several platforms, I would definitely include a test
case.
