I know it's rather bad form to reply to one's self, however, I wanted to
follow-up on this posting by saying that it has turned out to not be an
Apache/mod_perl problem at all. ab seems to be rather broken when
sending POST requests of any substantial size.
I had much greater success benchmarking with httperf, although it has a
compile time limit of 10,000 bytes per session event line. I rebuilt
httperf with a much greater line length limit, and our desired benchmark
behaviour completed successfully.
I apologize for wasting bandwidth.
