Hi,
They released 2.2 of Apache.
Changes in 2.2:
http://www.apache.org/dist/httpd/CHANGES_2.2
This is a patch config.m4 of Apache 2.2, have to start somewhere.
Well, before starting on 2.2 I checked, there are no differences between 2.0.52
and 2.0.55 in prefork.c and peruser compiles with 2.0.55.
How to start on 2.2 and how to apply my patch.
tar jzvf httpd-2.2.0.tar.bz2
cd httpd-2.2.0
patch -p1 < ../patches/httpd-2.0.52-peruser-0.1.6.patch
# which fails with some chunks on config.m4
# fix for chunks
patch -p1 < ../patches/httpd-2.2.0-config.m4-peruser-1
./buildconf
./configure --with-mpm=peruser
make
And yes, it doesn't compile.

Time to start looking at what they changed by looking at prefork or something.
Probably what will mean the biggest change from peruser perspective:
*) prefork, worker and event MPMs: Support a graceful-stop procedure:
Server will wait until existing requests are finished or until
"GracefulShutdownTimeout" number of seconds before exiting.
[Colm MacCarthaigh, Ken Coar, Bill Stoddard]
Because of the release there was/is even a small discussion on Slashdot about
the perchild MPM:
http://apache.slashdot.org/comments.pl?sid=169930&threshold=1&commentsort=0&tid=162&mode=thread&cid=14164245
No1 noticed that it was actually removed from this release.
