Maybe :-)

Secure mod_perl - i.e. mod_perl in an Apache that's shared with other web sites
mod_perl in any language supported by Linux
Interactive debugging of your perl on live requests inside a live Apache
See http://user-mode-linux.sourceforge.net/slides/wvu2002/wvu2002.htm
The section that's relevant here starts at
http://user-mode-linux.sourceforge.net/slides/wvu2002/img9.htm
There are also some wackier possibilities which I'm not sure are terribly
useful or practical, but would still be interesting to look at, such as:
Treating HTTP requests as processes, so
# ps uax
...
apache 1120 0.0 0.6 4388 1536 ? S 13:46 0:00 GET / HTTP/1.0
...
# kill -9 1120
or
# nice -20 1120
Treating HTTP requests as packets and using Netfilter to manipulate them.
