Since few languages on the iSeries are thread safe, the web server
actually starts a number of separate job instances to service the
various requests.  This allows ILE & OPM programs to be invoked for CGI
requests.

Actually, when I look at my linux systems, I always see a lot of httpd
tasks running as separate processes.  So it seems that even Standard
apache httpd doesn't use a thread pool either.  I may be wrong on this.

Really?  I'm no expert in PHP, but what would a web scripting language
require threading for?
