Hi,

I run this script on a Virtuozzo VM with Linux. It's a common apache
(apache 1, not 2) installation with PHP as module.

I must confess that I do not really understand the warning in the
documentation. What is a threaded web server module? What is that ZTS
mode? Anyway, same procedere when I execute the script on the command
line.

(BTW: If I execute the script in a Windowx XAMPP environment, apache
crashes).

Cheers,

Cem
