As always, thanks for the testcase.  I think I found the problem.  It's
hard to explain if you don;t know how the code works, but it boils down
to the fact that my last round of patches back in August were not
actually fixing the problem, but only working around it.  I'm hopeful
that I got it right this time.  I'm just generating a new snapshot.
Please give it another hit with the APR testsuite.


Thanks again,
Corinna
