Well, no. If you need a pool in any of the functions you put in
your callback tables: svn_diff_fns_t or svn_diff_output_fns_t,
put it in the private baton you pass into the svn_diff_diff* or

Those are read only functions and will never need a pool.

How on earth did we get ourselves into this mess? Isn't it easier
to 'fix Perl' as Joe Orton suggests on dev@apr, which seems the
biggest motivator for this change, and be done with it?
