Subversion makes ample use of subpools. If the apr_file_t for stderr was
placed into a subpool, then the thing would get closed when a pool cleanup

And I can't dup the file after it has been placed into an apr_file_t. The
first will continue to exist, and would get closed on cleanup.

Creating an apr_file_t for stderr/out/in is fine, but that cleanup is a
problem, and the dup is the only solution that I've figured out so far.
Other ideas are welcome; it certainly won't be "soon" that I get into that
code to do the dup... we have time.
