Well, no, we're pushing off the problem on to the people who package
things. :-)

Why not? When BDB 4.4 came out with auto-recovery feature, didn't
Collabnet start producing binaries that used that?

Those same distros aren't going to provide svn 1.5 right away either.
So if some packager wants to create their own svn 1.5 RPM, they can
package an APR 1.3 RPM (and possibly a new apache RPM) to go with it.

Either way, I'm not sure how this issue is relevant. Some distros
release things quickly, some slowly. Packagers for various distros
are used to dealing with this.

That's a possiblity, yeah. Then again, APR is an independent project.
 Not every api it exports is used by Apache. Just because something
goes into APR doesn't mean Apache has to use it.

I honestly don't remember the details, just that when we've had this
design discussion in the past, there seemed to be some consensus about
how a major part of the feature belongs in APR. Maybe we should dig
up those discussions.
