To reply to my own message,
I've tested this with mod_ssl loaded statically and as a DSO, it works
great. No more core dumps when built statically and the memory leak is just
about fixed. There's still a small memory leak somewhere, the httpd
processes still grow a bit after many (hundreds) gracefuls/restarts, but is
hardly noticable (maybe 100KB or so per process).
