I know; I didn't want to clutter the attempt to find the right
solution with such details :)

I'm having a hard time thinking of a reasonable way to expose enough
information so that the cleanup can be killed.  Some ugly helper
function could be exported by APR.  Or maybe force the address of the
cleanup function to be stored at offset 4 of the apr_mmap_t :)

(I actually prefer the latter...  It buys us time until the
hypothetical point where there are similar cleanup ordering problems
with other parts of APR and we have to come up with a solution that
solves today's problem and some new problem.)
