Hmm, I wonder if we should do a T&R with APR to give a "release"
that is separate from httpd-2.0.  I don't see any reason why we 
couldn't do this.  I just have no clue how to do the T&R.  My
understanding is that anyone with commit privs can do that.
I'll look into it though.

BUT, I think that the precedent with the APR-using projects is to
require a source checkout.  Subversion and httpd-2.0 both require 
the current CVS version of APR.  This allows APR to not have to 
maintain backward compatibility with "previous" releases (not
that we would anyway).

I think that defeats the purpose of APR.  If APR isn't doing it right,
then APR needs to be fixed.  APR should definitely support any platforms
that you are concerned about (i.e. Win32, etc.).  Which, of course, 
means that httpd-2.0 will run on those platforms as well.

The idea is that APR would better support these platforms than rewriting
the same code in mod_jk.  And, ideally, if you build around APR, you
will simplify the build process because APR will figure out all the OS
trickiness for you.

Correct, but the core jk components could still be built around APR.  
And, I imagine that the problem of other webservers has to do more with 
their specific OS than the web server (i.e. linking in APR).

And, hopefully, I'll have time at some point to actually back up what I
am saying with code.  I've just got a bazillion other things on my plate
right now.  =)  -- justin aka "APR evangelist"
