Oh dear. There's the problem.

Yes :-(

Issues with this:
- atexit() slots may be a scarce finite resource - no more than 32 are
- are there any issues with passing objects allocated by pools owned by one
apr instance to another?
- does libsvn_swig_py have an additional copy of apr, as well as all the
- it's worryingly inelegant

I'm pretty surprised that the link succeeded at all, as I know that libtool
is designed to outright refuse to link a shared library to a static library.

Note also that we already require (though we do not enforce) that
libsvn_swig_py be a shared library, with improper operation being the result
if it is static (issue 2202). In view of this, I think we can reasonably
require that apr also be a shared library.

Perhaps we can create some configury to warn about this issue.
