Can't shut down apache2

Mod_ruby folks,

I'm new to Ruby. I've been working with PHP for a long time
now, and recently I've been shopping around for something
more interesting.  Ruby looks like it might be just about right.

I've installed mod_ruby with apache2 on Gentoo. The only module
I have installed, beyond the usual suspects like mod_rewrite
and such that come stock, is libphp4.so.

Here's my problem: with mod_ruby 1.2.2, apache2 refuses to shut
down completely -- it leaves some number of process up after
a restart that only 'kill -9' will take down. The restart
style makes no difference -- both 'apache2 -k graceful' and
'apache2 -k restart' behave the same.

I just tried out mod_ruby 1.0.7. and it doesn't have this
problem.  I'd like to use the latest stable version, and since
I guess other people might have the same issue, I thought I'd
ask if anyone has any ideas.

Thanks.


Matthew
