I have posted questions to the PHP development list in the past and the main
reason that they gave for it still being experimental was that PHP as a
whole is not thread-safe and therefore if one of the extensions or libraries
was buggy and not thread-safe it could take down the whole apache instance.
 
Basically the impression I got was that no one in the PHP dev team saw
enough benefit in Apache 2 to warrant the testing and patching that would be
necessary to guarantee thread safety.  The also say that most issues would
only come up under high load, so it would be hard to see it at first.  Zend
published a whitepaper here
(http://www.zend.com/whitepapers/PHPandApache2-ZendWhitepaper.pdf) that
contains more details and basically urges users not to upgrade to Apache2.it
sounds very FUDish to me, and gives the impression that they don't want
users to upgrade because they are too lazy to test that configuration
thouroughly.
 
Basically I would like to know if RedHat did any specific patching or high
load testing in order to guarantee enterprise worthiness.  I would love to
use PHP with Apache 2 but I would just like to get some info on what it
takes to make it reliable.
