When I upgraded this morning, apache2 now fails to start.  I end up with
one apache2 process (instead of the number of children specified in
conf) which doesn't accept any http connections.  It also doesn't die
when I try /etc/init.d/apache2 stop, and I'm forced to kill it manually.

It shows up in ps aux like this:

www-data 16709  0.0  1.5  9860 3900 ?        S    11:44   0:00
/usr/sbin/apache2 -k start -DSSL

If I downgrade to 2.0.49-2, I'm able to start up successfully:
