Ack, starting clock with 72 hours to GA, contingent upon an absence
of problem reports (specificially regressions).
Six more cores since the last update of mod_mbox. Then twenty more
appeared with exactly the same timestamp: probably some bot pounding
the site.
Quick story: all the cores I've analyzed are mod_mbox crashes. None
in other parts of httpd.
+1 for GA based on running for 72 hours on www.apache.org without
crashes in the distributed code.

Brief analysis of some of the cores follows:

Guess that's gonna look real good in YOUR mailer... note a lot of
garbage, and header_only is set. It's a HEAD request.
