Ok +1 for the fix.

He's a big boy, he can hack the server some if he really wants to play
about with MAX setting.  Anyway he might learn something useful for future
releases.  My concern is only that people shouldn't accidently be able to
trash their server.  If they recompile a kludge then that's their problem.

I guess this means things are ok.

I think we all appreciate the work you've been  doing recently and I'm happy
to have contributed a little, albeit with a few innane suggestions.  You are
of course at liberty to release whatever you want, to whoever you want,
whenever you want.  We all are in this respect since the damned thing's
public property. ;)

However, wanting to release something doesn't make it less likely to be
flawed.  Apache's a complex system now, with a very few elements that might
benefit from a more thorough test.  The bigger the system gets the more
testing it needs and so the more the time that is needed before a release.
Getting frustated by the wait is all a part of this.

You don't want to quit do you?  Nope, I didn't think so.  So show it off.
I'm happy with the server now.  I wouldn't mind it being released.
