One I can think of - the threadpool API, but I'm willing to wait for
a richer feature set before calling 1.3 baked.

I'm pretty sure httpd would like to pick up 1.3.x by the time they are
ready to ship httpd-2.4, but that's a little ways off yet and still.

I really don't want the entire kitchen sink.  If we can keep this to the
essential nuts and bolts of a TLS conversation, and extracting information
about the client and server credentials, then we won't end up with an
extension of openssl that CAN'T be supported with cryptocme, gnutls or
other equally valid ssl/tls implementations.

We both need to consume openssl, for different elements.  In fact, I'm
thinking of refactoring all the pieces that are subject to FIPS-140
explicit implementations (which will just be stubbed out to openssl),
and these include every algorithm we have that is part of the openssl
project's fips_canister, such as sha1 hashes.

I definately don't want to see this handled piecemeal.  Please leave it in
place, and Joe please reconsider your veto.

The right way to handle it is to agree to agree on exactly how we will
change the ldap/dbm/dbd/xml/xlate/ssl library bindings to be dynamic
or modular.

Until we agree on that, I DON'T want to special-case ssl :(  It's wasted
effort.  Let's focus on addressing the real issues folks have identified
in the apr_ssl_* implementation?
